hot-backup.py fails on repositories with numbered names

Dear all,

hot-backup.py fails when the name of the copied repository has a
hyphen and digits.

sh-2.05b$ svnadmin create test-2008
sh-2.05b$ mkdir backup
sh-2.05b$ ./hot-backup.py test-2008 backup

svnadmin: 'backup/test-2008-0-1' exists and is non-empty
Unable to backup the repository.
----
The cause of the problem is that the revision comparator in
hot-backup.py misunderstands that test-2008-0 (2008-0) is newer than
test-2008-0-1 (0-1), and thus the next backup should be test-2008-0-1.
Tested environment is Debian GNU/Linux 3.1 (sarge) with trunk version
of hot-backup.py.in and python 2.3.5, but I think that the issue is
portable.
The attached is the patch possibly solving this issue.
Indentation is intentionally kept as the same as the original to
simplify the diff, so please fix it before committing.
