[osis-core] Regex News!

[Chris Little]

Patrick,

Sounds okay, but I'll go ahead and play the devil's advocate (read: look 
at things from Troy's position)...

I think one of Troy's desires was to be able to encode _anything_ as a 
valid osisGenRef, and I presume this change is partly/mostly intended to 
placate him.  Since spaces are part of some morphology codes, how should 
he encode those?  Non-breaking space?

If so, Troy, does that work for you?
