[PATCH] Teach "git diff -p" to locate PHP class methods

[Andreas Ericsson <ae@op5.se>]

Otherwise it will always print the class-name rather
than the name of the function inside that class.

While we're at it, reorder the gitattributes manpage to
list the built-in funcname pattern names in alphabetical
order.
