Built-in cherry 

This replaces the shell script git-cherry with a version written in C.

The behaviour of the new version differs from the original in two
points: it has no long help any more, and it is handling the (optional)
third parameter a bit differently.  Basically, it does the equivalent
of

   ours=`git-rev-list $ours ^$limit ^$upstream`

instead of

   ours=`git-rev-list $ours ^$limit`

Each commit between the fork-point (or <limit> if given) and <head> is
examined, and compared against the change each commit between the
fork-point and <upstream> introduces. If the change seems to be in
the upstream, it is shown on the standard output with prefix "+".
