gitk: Split out diff part in $commitinfo

So far we just parsed everything after the headers into the "comment"
bit of $commitinfo, including notes and -- if you gave weird options
-- the diff.

Split out the diff, if any, into a separate field.  It's easy to
recognize, since it always starts with /^diff/ and is preceded by an
empty line.

We take care to snip away said empty line.  The display code already
properly spaces the end of the message from the first diff, and
leaving another empty line at the end looks ugly.
