  This works.  Let's accept (some variant) or Skip's desired
functionality as os.path.splitprefix(); this avoid breaking existing
code and uses a name that's consistent with the others.  The result
can be (prefix, [list of suffixes]).  Trailing slashes should be
handled so that os.path.join(prefix, suffix) does the "right thing".
