Jeff King 7a4ee28f41 clone: add --branch option to select a different HEAD
We currently point the HEAD of a newly cloned repo to the
same ref as the parent repo's HEAD. While a user can then
"git checkout -b foo origin/foo" whichever branch they
choose, it is more convenient and more efficient to tell
clone which branch you want in the first place.

Based on a patch by Kirill A. Korinskiy.
