This is basically a fancy way of saying "git/$GIT_VERSION",
except that it is overridable at build-time and through the
environment. Which means that people who don't want to
advertise their git version (for privacy or security
reasons) can tweak it.

The global git_version_string currently lives in git.c, but
doesn't have anything to do with the git wrapper. Let's move
it into its own file, where it will be more appropriate to
build more version-related functions.

In most cases, plural-forms are unnecessary for Chinese. For example,
"apple" and "apples" are the same in Chinese, they are both translated
as "苹果". While there are exceptions, e.g., the plural form of "he",
"she" and "it" is "they" in English. In Chinese, "他(he)", "她(she)",
and "它(it)" have plural forms too, they are "他们", "她们", and "它们".

But what makes 'nplurals=1' hard to work right for Chinese is:

    #: bundle.c:192
    #, c-format
    msgid "The bundle requires this ref"
    msgid_plural "The bundle requires these %d refs"

In 9765b6ab (rebase: align variable content, 2011-02-06), the code
to error out was moved up one level. Unfortunately, one reference
to a function parameter wasn't rewritten as it should, leading to
the wrong parameter being errored on.

This error was propagated by 71786f54 (rebase: factor out reference
parsing, 2011-02-06) and merged in 78c6e0f3 (Merge branch
'mz/rebase', 2011-04-28).

The earlier "--keep-redundant-commit" series broke "cherry-pick"
that is given a commit whose change is already in the current
history. Such a cherry-pick would result in an empty change, and
should stop with an error, telling the user that conflict resolution
may have made the result empty (which is exactly what is happening),
but we silently dropped the change on the floor without any message
nor non-zero exit code.

Since 2cd9de3e (submodule add: always initialize .git/config entry) the
message "Submodule '\$name' (\$url) registered for path '\$sm_path'" is
printed every time cmd_init() is called, e.g. each time "git submodule
update" is used with the --init option.

This was not intended and leads to bogus output which can confuse users
and build systems. Apart from that the $url variable was not set after the
first run which did the actual initialization and only "()" was printed
in subsequent runs where "($url)" was meant to inform the user about the
upstream repo.

Fix that by moving the say command in question into the if block where the
url is initialized, restoring the behavior that was in place before the
2cd9de3e commit. While at it also remove the comment which still describes
the logic used before 2cd9de3e and add a comment about how things work now.

This test is pretty old and did not follow some of our more
modern best practices. In particular:

  1. It chdir'd all over the place, leaving later tests to
     deal with the fallout. Do our chdirs in subshells
     instead.

  2. It did not use test_must_fail.

  3. It did not use test_line_count.

  4. It checked for the non-existence of a ref by looking in the
     .git/refs directory (since we pack refs during clone
     these days, this will always be succeed, making the
     test useless).

     Note that one call to "-e .git/refs/..." remains,
     because it is checking for the existence of a symbolic
     ref, not a ref itself.
