[PATCH v3 0/2] Gettext support for Git

This patch series implements gettext support for git, making it possible to localize it. This should really be v2, but PATCH 1/2 had a trivial typo fix as v2, so I'm bumping the version of the whole series to v3 to avoid dual v3/v2 confusion.

Changes since v1:

  * Fixed all the things that Junio pointed out:

    - Tests that are too fragile to run everywhere (depend on
      locale/OS/implementation combinations) are now skipped unless
      TEST_GIT_GETTEXT_EXHAUSTIVE=1 is set.

    - fantasy-locale / real-locale filenames now make sense with
      respect to their tests.

    - Use `! test' instead of `test_expect_failure test`

    - Use the `>foo' redirection style instead of `> foo'.

  * Don't use `. gettext.sh' but `type gettext.sh && . gettext.sh'.

    The former failed on dash and Solaris's ksh.

  * Now compatible with the SunOS gettext implmentation, this needed:

    - #include <locale.h> in gettext.c, which is a good idea
       anyway. GNU libintl.h included it indirectly.

    - Define a Shell fallback that uses gettext(1). SunOS doesn't have
      gettext.sh, but it has a gettext command that shellscipts should
      use. It also needed a custom eval_gettext() wrapper.

    - Updating of INSTALL and Makefile docs to mention this.

  * The Perl tests can now be run with TEST_GIT_GETTEXT_EXHAUSTIVE=1
    through the t0202-gettext-perl.sh wrapper. The original patch
    didn't set GIT_TEXTDOMAINDIR, and I always ran the test.pl script
    manually.

  * Updated commit messages to reflect the changes above, and fixed a
    typo or two.
