IMO releases should use the revission number from where they where branched off
in their revission identifer (like r12653-pre-0.7-githash)
not devel HEAD using release versions+something but rather (r12653-githash)

If you want something easier to remember try using more than 10 chars
with lower case letters and numbers you can fit 46k revissions in 3 chars
and 4 should be enough until we switch vcs again
