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`

I'm not really sure if the limit behaviour change matches the original
intent of this feature; Yann, please holler if it doesn't.
