Good spotting, except that this string is a bit too specific to git and
GNU diff run in the C or ??_en locales.  An early draft of "git apply"
used to have the same string but the string was removed before the command
was released to the wild with a lot weaker condition (grep for "l10n" in
builtin/apply.c).
