[L10N] please review a batch l10n update for Git 2.2.0 final

Hi,

Only two days left for Git 2.2.0 final according to Git calendar (http://tinyurl.com/gitCal), but there is a new update for our L10N team to respond.

The change is so small, I can handle it. git-diff shows:

    -msgid "empty trailer token in trailer '%s'"
    +msgid "empty trailer token in trailer '%.*s'"

In order to catch up with Git 2.2.0 final, I update all affected l10n translations. If there are errors or you want to update yourself, please send me new pull request and I will rebase on your commit. What I have made:

    l10n: batch updates for one trivial change

    In order to catch up with the release of Git 2.2.0 final, make a batch
    l10n update for the new l10n change brought by commit d52adf1 (trailer:
    display a trailer without its trailing newline).

Because I update the .po files with msgmerge, this update also brings some format changes, so not panic. :) What I changed are:

    bg.po:msgid "empty trailer token in trailer '%.*s'"
    bg.po-msgstr "празна завършваща лексема в епилога „%.*s“"
    --
    ca.po:msgid "empty trailer token in trailer '%.*s'"
    ca.po-msgstr "fitxa de remolc buida en el remolc '%.*s'"
    --
    de.po:msgid "empty trailer token in trailer '%.*s'"
    de.po-msgstr "leerer Anhang-Token in Anhang '%.*s'"
    --
    fr.po:msgid "empty trailer token in trailer '%.*s'"
    fr.po-msgstr "symbole vide dans la ligne de fin '%.*s'"
    --
    sv.po:msgid "empty trailer token in trailer '%.*s'"
    sv.po-msgstr "tom släpradssymbol i släpraden \"%.*s\""
    --
    vi.po:msgid "empty trailer token in trailer '%.*s'"
    vi.po-msgstr "thẻ thừa trống rỗng trong phần thừa “%.*s”"
    --
    zh_CN.po:msgid "empty trailer token in trailer '%.*s'"
    zh_CN.po-msgstr "签名 '%.*s' 的键为空"

NOTE for Ralf: After I updated de.po, there are 3 fuzzies instead of one. I can only fix one of them.
