Regexp are greedy by default and they always return the first match,
so your first (.) will burn to the end of the string and then batch
the '/' and then there is nothing to match the (.*)$.  The solutions
are mailed back just make the last '/' optional (0 or 1 occurence)
which means when the first regexp doesn't match, it tries again not
being greedy and this time matches the optional '/'
