Fixes to #105 -- addition of glob support

Dmitry, here is that glob patch.  Note that I've had to tweak the spec that we discussed
*  The * wild-card pattern in Win32 / \*nix specific because of the different dir separators.
*  It was just easier to accept relative patterns but base them on the path of the relevant blacklist file.

Using Github for this type of collaboration is new to me so sorry if I've got this wrong.
