Add "--word-diff" to diff completion, since this is a common
desired option when looking at diffs.

Hi Gábor,

Here's a patch.  What do you think?

I was thinking it would be nice to complete --word-diff-regex, too,
and to be able to do

	git diff --color-words=<TAB>
	git diff --word-diff=<TAB>

but I couldn't find any examples of the latter to crib from, so I've
left the patch unmangled except for stealing a patch description from
a separate email.

Indeed, sending patches unmangled seems to be a common difficult step
when starting to contribute to projects like linux and git.  I wonder
if it would make sense to include some sort of
patch-sending-reviewing-tweaking-and-receiving tutorial to point to in
the documentation.

Thanks for keeping the completion code in good shape.
Jonathan
