[PATCH] i18n: move the trailing space out of translatable strings

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

I've got this with Vietnamese translation

    $ git status
    HEAD được tách rời từorigin/master

One does not need to understand Vietnamese to see that a space is
missing before "origin/master" and this is because the original string
has a trailing space, but the translated one omits it.

I could fix vi.po alone, but it'd be better to avoid similar mistakes
for all translations by moving the trailing space out of all
translatable strings (*). This is inline with how we handle newlines
(e.g. *printf_ln wrappers) but it's not widespread enough to make new
*printf_space wrappers.

(*) the strings are detected by

    make pot; msgcat --no-wrap po/git.pot|grep 'msgid.* "$'

and if you do it after this patch, you will see maybe 3 matched lines
from git-bisect.sh and git-am.sh that I didn't bother to fix.

 BTW "msgcat...|grep 'msgid.*\n"$'" gives 159 matches. Low hanging
 fruit..
