Allow multiple file patterns on the command line.

When debugging desyncs, it's useful to be able to re-run a bunch of
previous failures. For example:

  python regression-test $(cat previous-fails.txt)

To be able to do this it's necessary to be able to specify multiple
patterns on the command line. This is in keeping with other Unix tools
that do the same.
