[PATCH] Revert diffstat back to English

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

This reverts the i18n part of 7f81463 (Use correct grammar in diffstat
summary line - 2012-02-01) but still keeps the grammar correctness for
English. It also reverts b354f11 (Fix tests under GETTEXT_POISON on
diffstat - 2012-08-27). The result is diffstat always in English
for all commands.

This helps stop users from accidentally sending localized
format-patch'd patches.

 The "for now" sounds reasonable. Minimum annoyance is always good
 especially in a (largely?) volunteer-driven development environment
 like git. So I revert the i18n effect. Note that I don't optimize the
 changes for English only. The i18n might come back some day if we
 find a good way to do it.

 Git is still partly i18n-ized, turning a few strings back does not
 seem a big regression.

 If you mean projectlang vs a local language, I looked into that and I
 don't think we could support two non-C languages using standard
 gettext interface. So it's either "C vs another", or make use of
 unofficial gettext features, or roll your own.
