Log:
Use last changed revision number instead of last-commited-somewhere-in-repo

svnversion without options returns the most recent revision in the repo
at the time of the last svn update/checkout even if that revision
didn't hold any changes in the current path. Not very useful as a
reference. Better is to ask for the last changed revision with -c.
BUT: -c option for some reason always considers svn working copy
as having mixed sources. We're only interested in the last part so
we strip the beginning revision if it's there.
As a result if your WC really has mixed sources, that will not be
visible in the version number...
