I wouldn't call these better (or worse) than regexes, but a slight variation
on the above:

marker = s.index('/CHECKEDOUT')
branch = s [s.rindex('/', 0, marker) + 1 : marker]

This version will throw exceptions when the marker isn't found, which may or
may not be preferable under the circumstances.
