git apply didn't catch error? [was Re: [PATCH] Documentation/diff-options.txt: unify options]

JCH> $ wget http://article.gmane.org/gmane.comp.version-control.git/104017/raw
JCH> $ git apply raw
JCH> error: diff-options.txt: No such file or directory
JCH> $ echo $?
JCH> 1
$ cd Documentation
$ git apply ../raw
$ echo $?
0
So then one thinks "why of course, the changes we already applied."
However if one makes some sneaky changes:
$ diff ../raw.original raw
46c46
< index 5721548..b05503a 100644
---

index 6721548..c05503a 100644

< +-w::

+-w::ZZZZZZZZZZZZZZZZZZ

One gets the same $?=0. git apply should scream instead of silently
returning 0 and doing nothing. git version 1.6.0.6.
