[PATCH] gitattributes: Fix subdirectory attributes specified from root directory

Signed-off-by: Matthew Ogilvie <redacted>

I've been working on adding crlf attribute support for git-cvsserver, and
noticed this little issue.  I've included some tests and a fix.
The cvsserver stuff is still incomplete and not included.

There are a couple of things I'm not sure about, but seem to make
the most sense the way I coded it:

1. A test of the form "attr_check /a/i a/i" (notice the prefixed '/'
in the pathname) will "pass" without this patch, but will not
"pass" with this patch.  This seems slightly more correct, but
I'm not sure.

2. The first (non-setup) test in t0003-attributes.sh actually
batches up several checks as one test.  I figured there should be
some limit on how many individual checks get batched into one,
so I started a second test, but I could see an argument to just
include the new checks in the existing batch.
