[PATCH] Add diff directives to gitattributes

Hi hackers,

Attached is a patch which adds diff= directives to .gitattributes for C,
Perl and (X|SG)ML files.  This makes word diffs and the function
indicator in the diff chunk header and more useful.

Subject: [PATCH] Add diff directives to .gitattributes
