Nope.  And in fact, it looks like any file in a subdir is handled
incorrectly.

Hmm.  If I use _both_ -p0 and --posix, I can get the patch to apply properly
to files in subdirs, but then my patch won't create files anymore.

According to my patch man page, it appears CVS is relying on some POSIX
behavior which tells patch to read the filename on the 'Index:' line and not
the later 'diff', '---', and '+++' lines.  Unfortunately, my implementation
of patch appears to then ignore created files, though from the man page it
doesn't appear that it is supposed to.

I can correct the problem by editing the diff CVS creates by hand and
inserting the proper subdirs in front of filenames on the 'diff', '---', and
'+++' lines.

I used to think people were crazy to get tatoos.  Nowadays, I envy
them that clarity of thought.  There was at least one point in their lives
when they thought they knew what they were doing.  They could walk into a
tatoo parlor and say, "I want a big old pig, in red and black, with flames
shooting out of its nose!  And I want it right there!  That's who I am!"
