Re: [PATCH] Add "--summary" option to git diff.

Remove the need to pipe git diff through git apply to
get the extended headers summary.

Hmph...

The next branch with this and other patches applied seems to
misbehave.

It makes glibc unhappy with 

PAGER= ./git whatchanged -B -C --stat --summary --no-merges --diff-filter=RC

and "*** glibc detected *** malloc(): memory corruption: xxx ***"

but not with this:

PAGER= ./git whatchanged -B -C --no-merges --diff-filter=RC

nor with this:

PAGER= ./git whatchanged -B -C --summary --no-merges --diff-filter=RC

works just fine, so this is _not_ your fault, and I know who to
harrass ;-).
