rm: resolving by removal is not a warning-worthy event
When resolving a conflict on a path in favor of removing it, using

$ git merge side-branch
$ edit conflicted-path-1

The removal by "git rm" does get performed, but an uninitiated user

before being able to remove it???"
The message is coming from "update-index --refresh" that is called

relative to the index without the "-f" option. We somehow ended up

ci: don't update Homebrew
Lately our GCC macOS build job on Travis CI has been erroring out
while installing dependencies with:
+brew link gcc@8
Error: No such keg: /usr/local/Cellar/gcc@8
The command "ci/install-dependencies.sh" failed and exited with 1 during .
Now, while gcc@8 is still pre-installed (but not linked) and would be
perfectly usable in the Travis CI macOS image we use [1], it's at
version 8.2. However, when installing dependencies we first
explicitly run 'brew update', which spends over two minutes to update
itself and information about the available packages, and it learns
about GCC 8.3. After that point gcc@8 exclusively refers to v8.3,
and, unfortunately, 'brew' is just too dumb to be able to do anything
with the still installed 8.2 package, and the subsequent 'brew link
gcc@8' fails. (Even 'brew uninstall gcc@8' fails with the same
error!)
Don't run 'brew update' to keep the already installed GCC 8.2 'brew
link'-able. Note that in addition we have to 'export
HOMEBREW_NO_AUTO_UPDATE=1' first, because 'brew' is so very helpful
that it would implicitly run update for us on the next 'brew install
<pkg>' otherwise.
Disabling 'brew update' has additional benefits:
- It shaves off 2-3mins from the ~4mins currently spent on
installing dependencies, and the macOS build jobs have always been
prone to exceeding the time limit on Travis CI.
- Our builds won't suddenly break because of the occasional Homebrew
breakages [2].
The drawback is that we'll be stuck with slightly older versions of
the packages that we install via Homebrew (Git-LFS 2.5.2 and Perforce
2018.1; they are currently at 2.7.2 and 2019.1, respectively). We
might want to reconsider this decision as time goes on and/or switch
to a more recent macOS image as they become available.

To make sure that the previously displayed progress line is completely

545dc345eb (progress:

calculations to figure out how many characters it needs to overwrite

Use the just introduced term_clear_line() helper function to, well,
clear the last line, making all these calculations unnecessary, and
thus simplifying the code considerably.
Three tests in 't5541-http-push-smart.sh' 'grep' for specific text

these three tests fail without relaxing their 'grep' pattern, but the
third looks for the absence of the pattern, so it still succeeds, but
without the adjustment would potentially hide future regressions.

rebase: fix garbled progress display with '-x'
When running a command with the 'exec' instruction during an
interactive rebase session, or for a range of commits using 'git
rebase -x', the output can be a bit garbled when the name of the
command is short enough:
$ git rebase -x true HEAD~5
Executing: true
Executing: true
Executing: true
Executing: true
Executing: true)
Successfully rebased and updated refs/heads/master.
Note the ')' at the end of the last line. It gets more garbled as the
range of commits increases:
$ git rebase -x true HEAD~50
Executing: true)
[ repeated 3 more times ]
Executing: true0)
[ repeated 44 more times ]
Executing: true00)
Successfully rebased and updated refs/heads/master.
Those extra numbers and ')' are remnants of the previously displayed
"Rebasing (N/M)" progress lines that are usually completely
overwritten by the "Executing: <cmd>" lines, unless 'cmd' is short and
the "N/M" part is long.
Make sure that the previously displayed "Rebasing (N/M)" line is
cleared by using the term_clear_line() helper function added in the
previous patch. Do so only when not being '--verbose', because in
that case these "Rebasing (N/M)" lines are not printed as progress
(i.e. as lines with '\r' at the end), but as "regular" output (with
'\n' at the end).
A couple of other rebase commands print similar messages, e.g.
"Stopped at <abbrev-oid>... <subject>" for the 'edit' or 'break'
commands, or the "Successfully rebased and updated <full-ref>." at the
very end. These are so long that they practically always overwrite
that "Rebasing (N/M)" progress line, but let's be prudent, and clear
the last line before printing these, too.
In 't3420-rebase-autostash.sh' two helper functions prepare the
expected output of four tests that check the full output of 'git
rebase' and thus are affected by this change, so adjust their
expectations to account for the new line clearing.
Note that this patch doesn't completely eliminate the possibility of
similar garbled outputs, e.g. some error messages from rebase or the
"Auto-merging <file>" message from within the depths of the merge
machinery might not be long enough to completely cover the last
"Rebasing (N/M)" line. This patch doesn't do anything about them,
because dealing with them individually would result in way too much
churn, while having a catch-all term_clear_line() call in the common
code path of pick_commits() would hide the "Rebasing (N/M)" line way
too soon, and it would either flicker or be invisible.

t5551: test usage of chunked encoding explicitly
When run using GIT_TEST_PROTOCOL_VERSION=2, a test in t5551 fails
because 4 POSTs (probe, ls-refs, probe, fetch) are sent instead of 2
(probe, fetch).
One way to resolve this would be to relax the condition (from "= 2" to
greater than 1, say), but upon further inspection, the test probably
shouldn't be counting the number of POSTs. This test states that large
requests are split across POSTs, but this is not correct; the main
change is that chunked transfer encoding is used, but the request is
still contained within one POST. (The test coincidentally works because
Git indeed sends 2 POSTs in the case of a large request, but that is
because, as stated above, the first POST is a probing RPC - see
post_rpc() in remote-curl.c for more information.)

foreach --recursive <subcommand> --<option>
inside the first level submodule. Note that the double dash in front of
the subcommand is missing.
This problem starts to arise only recently, as the
PARSE_OPT_KEEP_UNKNOWN flag for the argument parsing of git submodule
foreach was removed in commit
a282f5a906. Hence, the unknown option is
complained about now, as the argument parsing is not properly ended by
the double dash.
This commit fixes the problem by adding the double dash in front of the
subcommand during the recursion.

pager: add a helper function to clear the last line in the terminal
There are a couple of places where we want to clear the last line on
the terminal, e.g. when a progress bar line is overwritten by a
shorter line, then the end of that progress line would remain visible,
unless we cover it up.
In 'progress.c' we did this by always appending a fixed number of
space characters to the next line (even if it was not shorter than the
previous), but as it turned out that fixed number was not quite large
enough, see the fix in
9f1fd84e15 (progress: clear previous progress
update dynamically, 2019-04-12). From then on we've been keeping
track of the length of the last displayed progress line and appending
the appropriate number of space characters to the next line, if
necessary, but, alas, this approach turned out to be error prone, see
the fix in
1aed1a5f25 (progress: avoid empty line when breaking the
progress line, 2019-05-19). The next patch in this series is about to
fix a case where we don't clear the last line, and on occasion do end
up with such garbage at the end of the line. It would be great if we
could do that without the need to deal with that without meticulously
computing the necessary number of space characters.
So add a helper function to clear the last line on the terminal using
an ANSI escape sequence, which has the advantage to clear the whole
line no matter how wide it is, even after the terminal width changed.
Such an escape sequence is not available on dumb terminals, though, so
in that case fall back to simply print a whole terminal width (as
reported by term_columns()) worth of space characters.
In 'editor.c' launch_specified_editor() already used this ANSI escape
sequence, so replace it with a call to this function.
