[PATCH v6 1/7] i18n: New keywords for xgettext extraction from sh

[Jiang Xin]

Since we have additional shell wrappers (gettextln and eval_gettextln)
for gettext, we need to take into account these wrappers when running
'make pot' to extract messages from shell scripts.

[PATCH v6 2/7] i18n: rebase: mark messages for translation

[Jiang Xin]

Mark messages in git-rebase.sh for translation.  While doing this
Jonathan noticed that the comma usage and sentence structure of the
resolvemsg was not quite right, so correct that and its cousins in
git-am.sh and t/t0201-gettext-fallbacks.sh at the same time.

Some tests would start to fail with GETTEXT_POISON turned on after
this update.  Use test_i18ncmp and test_i18ngrep where appropriate
to mark strings that should only be checked in the C locale output
to avoid such issues.

[PATCH v6 3/7] i18n: Rewrite gettext messages start with dash

[Jiang Xin]

Gettext message in a shell script should not start with '-', one
workaround is adding '--' between gettext and the message, like:

    gettext -- "--exec option ..."

But due to a bug in the xgettext extraction, xgettext can not
extract the actual message for this case. Rewriting the message
is a simpler and better solution.

[PATCH v6 4/7] Remove obsolete LONG_USAGE which breaks xgettext

[Jiang Xin]

The obsolete LONG_USAGE variable has the following message in it:

    A'\''--B'\''--C'\''

And such complex LONG_USAGE message will break xgettext when
extracting l10n messages. But if single quotes are removed from
the message, xgettext works fine on 'git-rebase.sh'.

Since there is a modern OPTIONS_SPEC variable in use in this
script, it's safe to remove the obsolete USAGE and LONG_USAGE
variables.

I've retitled it and swapped the paragraphs around when queuing
this.  LONG_USAGE and USAGE are not just "obsolete" but completely
unused, so they should be removed, even if xgettext did not have a
bug to choke on their contents.

Thanks.

[PATCH v6 5/7] i18n: am: mark more strings for translation

[Jiang Xin]

Mark strings in 'git-am.sh' for translation. In the last chunk, I
changed '$1' to '-b/--binary' for this reason:

 * First, if there is a variable in the l10n message, we could not use
   gettext. Because the variable will be expanded (evaluated) and will
   never match the entry in the po file.

 * Second, if there is a positional parameter ($1, $2,...) in the
   message, we could not use eval_gettext either. Because eval_gettext
   may be a wapper for gettext, and the positional parameter would
   lose its original context.

Also reduce one indentation level for one gettextln clause introduced
in commit de88c1c.

Thanks. I've reworded the rationale for -b/--binary, though, as the
above sounds as if we are clueless as to how to i18n this message
properly even if we wanted to, which is not the case.

    Mark strings in 'git-am.sh' for translation. In the last chunk,
    change '$1' to '-b/--binary', as it is not worth turning this
    message to "The %s option has been..." and using printf on it.

[PATCH v6 6/7] Remove dead code which contains bad gettext block

[Jiang Xin]

Found this dead code when I examine gettext messages in shell scripts
start with dash ('-' or '--'). An error will be raised for this case,
like:

    $ gettext "-d option is no longer supported.  Do not use."
    gettext: missing arguments

Indead, this code has been left as dead for a long time, as Jonathan
points out:

    The git am -d/--dotest option has errored out with a message
    since e72c7406 (am: remove support for -d .dotest, 2008-03-04).
    The error message about lack of support was eliminated along
    with other cleanups (probably by mistake) a year later by
    removing the option from the option table in 98ef23b3 (git-am:
    minor cleanups, 2009-01-28).

    But the code to handle -d and --dotest stayed around even though
    ever since then it could not be tripped.  Remove this dead code.

[PATCH v6 7/7] i18n: merge-recursive: mark strings for translation

[Jiang Xin]

Mark strings in merge-recursive for translation.

Some tests would start to fail with GETTEXT_POISON turned on after
this update.  Use test_i18ncmp and test_i18ngrep where appropriate
to mark strings that should only be checked in the C locale output
to avoid such issues.
