While the regex discussion is interesting, the original post was about the
best way of extracting the number at the end of the string. It horrified me
(kind of) that Art proposed the idea of replacing all prefix-characters
with spaces, which is a valid use case for a different problem, but only
serves to add overhead to the problem at hand.
