Shallow clones (--depth X) lack the N tag used to compute the revision number: use 'git-YYYY-MM-DD-hhhhhhh' as revision, where hhhhhhh is the short git hash. Snapshots from gitweb do not have git information at all, but they have the short git hash in the directory name: append it to the release number.
