Sanitize $new

Hi! I realize you're just starting out =)

We are looking for a module like this, and were going to either implement it or use an external implementation like EXT2 and then import to Drupal from there... so personally I can help you out with this module, just ask! (I'm on IRC #drupal regularly)

For now I found out that the "short identifier" for a repository doesn't work (at least for me) if you type in spaces. So I think you can add a line to fix that, see patch below.

Index: oai_pmh.module
===================================================================
RCS file: /cvs/drupal-contrib/contributions/modules/oai_pmh/oai_pmh.module,v
retrieving revision 1.1
diff -r1.1 oai_pmh.module

>     $new = preg_replace('/[^a-z0-9_-]+/i', '_', trim($new));

Cheers!
