[PATCH] apply.c: --exclude=fnmatch-pattern option.

Browse Source 
Adds --exclude=pattern option to the "git-apply" command.  This
was useful while reimporting the BKCVS patchset dump of the
Linux kernel, starting at 2.4.0 and ending at 2.6.12-rc2 Ingo
announced some time ago to exclude BitKeeper directory.
