While I'm certain that there are a lot of things to object to in this
patch, it shows 90% of what is needed to use gettext to translate
the portions of git written in c, without involving undesired gnu
infrastructure such as automake.

Makefile adds necessary rules for generating git.pot and for building
and installing compiled message catalogs (.mo) from text message
catalogs (.po).  It also adds a gettext support header and source file.

Minimal changes are made to git to use the requested LC_CTYPE and
LC_MESSAGES, and some messages for 'git status' are marked for
translation.

When I provided a gibberish translation of a message:
#: wt-status.c:87
msgid "# Changed but not updated:"
msgstr "# Changes not blah blah blah"

running 'git status' used the translation:
$ git status
# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
#
# Changes not blah blah blah
...

I ran with 'make install' and prefix set in config.mak.  It didn't seem
to work when running from the source directory, and it may or may not
work with runtime prefix.

Thanks a lot for this patch.

I'm having some trouble getting it to work though. I did:

    make pot

That made the po/git.pot file with all the relevant messages. Then I
made a po/is.po in poedit which has stuff like:

    #: wt-status.c:598
    msgid "On branch "
    msgstr "A greininni "

    #: wt-status.c:605
    msgid "Not currently on any branch."
    msgstr "Ekki á grænni grein.

I did:

    make prefix=/usr all
    sudo make prefix=/usr install

But any invocation of my new git-status (I uninstalled my system git
first) with either LC_ALL, LC_MESSAGES or LC_CTYPE set to is, is_IS or
is_IS.UTF-8 doest't yield the desired results:

    $ strings /usr/share/locale/is/LC_MESSAGES/git.mo |grep grein
    nni grein.
    A greininni

it doesn't seem to spot the file:

    $ strace git status 2>&1|grep locale
    open("/usr/lib/locale/locale-archive", O_RDONLY|O_LARGEFILE) = -1
ENOENT (No such file or directory)
    open("/usr/share/locale/locale.alias", O_RDONLY) = 3
    open("/usr/lib/locale/is/LC_MESSAGES", O_RDONLY) = -1 ENOENT (No
such file or directory)
    open("/usr/share/locale-langpack/is/LC_MESSAGES", O_RDONLY) = 3
    open("/usr/share/locale-langpack/is/LC_MESSAGES/SYS_LC_MESSAGES",
O_RDONLY) = -1 ENOENT (No such file or directory)
    open("/usr/lib/locale/is/LC_CTYPE", O_RDONLY) = -1 ENOENT (No such
file or directory)
    open("/usr/share/locale-langpack/is/LC_CTYPE", O_RDONLY) = -1
ENOENT (No such file or directory)
    open("share/locale/",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 5
    open("share/locale/.gitignore", O_RDONLY|O_LARGEFILE) = -1 ENOENT
(No such file or directory)
    open("share/locale/is/",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 6
    open("share/locale/is/.gitignore", O_RDONLY|O_LARGEFILE) = -1
ENOENT (No such file or directory)
    open("share/locale/is/LC_MESSAGES/",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 7
    open("share/locale/is/LC_MESSAGES/.gitignore",
O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)

And the UI remains untranslated.

I'm probably doing something very silly. I'd appreciate some help if
you can spot what it is, if I can get this working I can start
submitting some i18n patches.
