Since we will be transitioning to git, stop considering svn the primary source.
If HEAD is a git-svn revision, return the svn revision number as before
(this means that if you check out old versions they keep their previously
canonical version numbers) but if it's not, then just print the short SHA1.

Only I ever used this that I know of, and now we are migrating to git it's
not needed (and won't work correctly, since we won't be svn-derived).

commit ID in the version string, much like is done for repos tracked
with bzr. FS#11297

"git log .. -1" only shows one commit (the last one), so extract the last line (git-svn-id:..) with tail -n 1, instead of the first line (which is the committer's message in case of multi lines body)
