[PATCH] git apply: binary files differ can be applied with -pN (N>1).

[Jiang Xin <worldhello.net@gmail.com>]

When patch file generated against two non-git directories using
'git diff --binary --no-index' without '--no-prefix', the patch
file has patch level greater then 1, and should be applied with
'-p2' option. But it does not work if there are binary differ
in the patch file, it is because in one case the patch level is
not properly handled.
