I see you moved the two bits meant only to be useful during the
review to the commit message proper.  The reason why I omitted the
"Originally, ..." part was because those who are reading "git log
-p" output would not know what the earlier draft had.

I do not mind it either way, though, so let's take this version.

However, I'd have to drop gitk-git/ bit; that part of the tree is
maintained separately and comes from Paul's gitk repository.  I'll
forward only that part of the patch to him when this feature
graduates to 'master'.

Thanks.
