Drawback: The version string is no longer a valid git identifier.
For this reason the 'g' short hash prefix has been removed.
Exception: When building directly from a tag this behaves exactly like the previous behavior.
This allows formatting release versions with precision i.e. v0.9.2
This also allows arbitrary topicbranch names i.e. v0.9.1-glibc-compat
