pager: set COLUMNS to term_columns()

After we invoke the pager, our stdout goes to a pipe, not the
terminal, meaning we can no longer use an ioctl to get the
terminal width. For that reason, ad6c3739a3 (pager: find out
the terminal width before spawning the pager, 2012-02-12)
started caching the terminal width.

But that cache is only an in-process variable. Any programs
we spawn will also not be able to run that ioctl, but won't
have access to our cache. They'll end up falling back to our
80-column default.

You can see the problem with:

  git tag --column=row

Since git-tag spawns a pager these days, its spawned
git-column helper will see neither the terminal on stdout
nor a useful COLUMNS value (assuming you do not export it
from your shell already). And you'll end up with 80-column
output in the pager, regardless of your terminal size.

We can fix this by setting COLUMNS right before spawning the
pager. That fixes this case, as well as any more complicated
ones (e.g., a paged program spawns another script which then
generates columnized output).

SZEDER Gábor [Mon, 30 Apr 2018 09:31:53 +0000 (11:31 +0200)] 
coccinelle: avoid wrong transformation suggestions from commit.cocci

The semantic patch 'contrib/coccinelle/commit.cocci' added in
2e27bd7731 (treewide: replace maybe_tree with accessor methods,
2018-04-06) is supposed to "ensure that all references to the
'maybe_tree' member of struct commit are either mutations or accesses
through get_commit_tree()".  So get_commit_tree() clearly must be able
to directly access the 'maybe_tree' member, and 'commit.cocci' has a
bit of a roundabout workaround to ensure that get_commit_tree()'s
direct access in its return statement is not transformed: after all
references to 'maybe_tree' have been transformed to a call to
get_commit_tree(), including the reference in get_commit_tree()
itself, the last rule transforms back a 'return get_commit_tree()'
statement, back then found only in get_commit_tree() itself, to a
direct access.

Unfortunately, already the very next commit shows that this workaround
is insufficient: 7b8a21dba1 (commit-graph: lazy-load trees for
commits, 2018-04-06) extends get_commit_tree() with a condition
directly accessing the 'maybe_tree' member, and Coccinelle with
'commit.cocci' promptly detects it and suggests a transformation to
avoid it.  This transformation is clearly wrong, because calling
get_commit_tree() to access 'maybe_tree' _in_ get_commit_tree() would
obviously lead to recursion.  Furthermore, the same commit added
another, more specialized getter function get_commit_tree_in_graph(),
whose legitimate direct access to 'maybe_tree' triggers a similar
wrong transformation suggestion.

Exclude both of these getter functions from the general rule in
'commit.cocci' that matches their direct accesses to 'maybe_tree'.
Also exclude load_tree_for_commit(), which, as static helper funcion
of get_commit_tree_in_graph(), has legitimate direct access to
'maybe_tree' as well.

The last rule transforming back 'return get_commit_tree()' statements
to direct accesses thus became unnecessary, remove it.

Avoid multiple PREFIX definitions

The short and sweet PREFIX can be confused when used in many places.

Rename both usages to better describe their purpose. EXEC_CMD_PREFIX is
used in full to disambiguate it from the nearby GIT_EXEC_PATH.

The PREFIX in sideband.c, while nominally independant of the exec_cmd
PREFIX, does reside within libgit[1], so the definitions would clash
when taken together with a PREFIX given on the command line for use by
exec_cmd.c.

Noticed when compiling Git for Windows using MSVC/Visual Studio [1] which
reports the conflict beteeen the command line definition and the
definition in sideband.c within the libgit project.

[1] the libgit functions are brought into a single sub-project
within the Visual Studio construction script provided in contrib,

Johannes Schindelin [Sat, 21 Apr 2018 11:14:08 +0000 (13:14 +0200)] 
gettext: avoid initialization if the locale dir is not present

The runtime of a simple `git.exe version` call on Windows is currently
dominated by the gettext setup, adding a whopping ~150ms to the ~210ms
total.

Given that this cost is added to each and every git.exe invocation goes
through common-main's invocation of git_setup_gettext(), and given that
scripts have to call git.exe dozens, if not hundreds, of times, this is
a substantial performance penalty.

This is particularly pointless when considering that Git for Windows
ships without localization (to keep the installer's size to a bearable
~34MB): all that time setting up gettext is for naught.

To be clear, Git for Windows *needs* to be compiled with localization,
for the following reasons:

- to allow users to copy add-on localization in case they want it, and

- to fix the nasty error message

BUG: your vsnprintf is broken (returned -1)

  by using libgettext's override of vsnprintf() that does not share the
  behavior of msvcrt.dll's version of vsnprintf().

So let's be smart about it and skip setting up gettext if the locale
directory is not even present.

Since localization might be missing for not-yet-supported locales, this
will not break anything.
