use persistent memory for rejected paths

An aborted merge prints the list of rejected paths as part of the
error message. Since commit f66caaf9 (do not overwrite files in
leading path), some of those paths do not have static buffers, so
we have to keep a copy. Use string_list's to accomplish this.

This changes the order of the list to the order in which the paths
are processed. Previously, it was reversed.

tests: add some script lint checks

There are some common but minor errors we tend to make in
writing test scripts:

  1. Scripts are left non-executable. This is not usually
     noticed immediately because "make test" does not need
     the bit, but it is a matter of git policy to make them
     executable (and is a slight convenience when running
     individual scripts).

  2. Two scripts are allocated the same number. Usually this
     happens on separate branches, and the problem only
     comes about during a merge. But since there is no
     textual conflict, the merger would have to be very
     observant to notice.

     This is also a minor error, but can make GIT_SKIP_TESTS
     ambiguous.

This patch introduces a "test-lint" target which checks
both. It is not invoked by default. You can invoke it as
"make test-lint", or you can make it a prerequisite of
running the tests by specifying "TEST_LINT = test-lint" in
your config.mak or on the command line.

update-index: migrate to parse-options API

--refresh and --really-refresh accept flags (like -q) and modify
an error indicator.  It might make sense to make the error
indicator global, but just pass the flags and a pointer to the error
indicator in a struct instead.

--cacheinfo wants 3 arguments.  Use the OPTION_LOWLEVEL_CALLBACK
extension to grab them and PARSE_OPT_NOARG to disallow the "sticked"
--cacheinfo=foo form.  (The resulting message

$ git update-index --cacheinfo=foo
error: option `cacheinfo' takes no value

is unfortunately incorrect.)

--assume-unchanged and --no-assume-unchanged probably should use the
OPT_UYN feature; but use a callback for now so the existing MARK_FLAG
and UNMARK_FLAG values can be used.

--stdin and --index-info are still constrained to be the last argument
(implemented using the OPTION_LOWLEVEL_CALLBACK extension).

--unresolve and --again consume all arguments that come after them
(also using OPTION_LOWLEVEL_CALLBACK).

The order of options matters.  Each path on the command line is
affected only by the options that come before it.  A custom
argument-parsing loop with parse_options_step() brings that about.

In exchange for all the fuss, we get the usual perks: support for
un-sticked options, better usage error messages, more useful -h
output, and argument parsing code that should be easier to tweak
in the future.

So now in your builtin command, instead of passing prefix around,
when you want to convert a user-supplied path to a cwd-relative
path, you can use startup_info->prefix directly.

Caveat: As with the return value from setup_git_directory_gently(),
startup_info->prefix would be NULL when the original cwd is not a
subdir of the toplevel.

Longer term, this would allow the prefix to be reused when several

parse-options provides a variety of option behaviors, including
OPTION_CALLBACK, which should take care of just about any sane
behavior.  All supported behaviors obey the following constraint:

 A --foo option can only accept (and base its behavior on)
 one argument, which would be the following command-line
 argument in the "unsticked" form.

Alas, some existing git commands have options that do not obey that
constraint.  For example, update-index --cacheinfo takes three
arguments, and update-index --resolve takes all later parameters as
arguments.

Introduces an OPTION_LOWLEVEL_CALLBACK backdoor to parse-options so
such option types can be supported without tempting inventors of other
commands through mention in the public API.  Commands can set the
callback field to a function accepting three arguments: the option
parsing context, the option itself, and a flag indicating whether the
the option was negated.  When the option is encountered, that function
is called to take over from get_value().  The return value should be
zero for success, -1 for usage errors.

since v1.6.4-rc0~71 (parse-options: add parse_options_check to
validate option specs, 2009-07-09) this mistake is flagged with

error: `--option` uses incompatible flags LASTARG_DEFAULT and OPTARG

and an exit status representing an error in commandline usage.

Unfortunately that which might confuse scripters calling such an
erroneous program into thinking the _script_ contains an error.
Clarify that it is an internal error by dying with a message beginning
"error: BUG: ..." and status 128.

While at it, clean up parse_options_check to prepare for more checks.

Long term, it would be nicer to make such checks happen at compile
time.

git-rm.txt: Fix quoting

Literal " produces typographically incorrect quotations, but "works" in
most circumstances. In the subheadings of git-rm.txt, it "works" for the
html backend but not for the docbook conversion to nroff: double "" and
spurious double spaces appear in the output.

Replace "incorrect" quotations by ``correct'' ones, and fix other
"quotations" which are really `code fragments`.

This should make git-rm.txt "-clean.

parse-options: Don't call parse_options_check() so much

parse_options_check() is being called for each invocation of
parse_options_step which can be quite a bit for some commands. The
commit introducing this function cb9d398 (parse-options: add
parse_options_check to validate option specs., 2009-06-09) had the
correct motivation and explicitly states that parse_options_check()
should be called from parse_options_start(). However, the implementation
differs from the motivation. Fix it.

If someone runs "git st", the command "git status" is not suggested
because it's not one of the closest levenshtein-neighbour.

Reserve the distance of 0 for common commands where the entered command
is a prefixe, as these are often more likely to be what the user meant.

This way, "git status" is the first suggestion, while a list of possible
typos are still suggested as well.
