 I bumped into this odd bug, in preview_theme()

 {{{
 var_dump($_GET['template']); // foo-bar
         $_GET['template'] = preg_replace('|[^a-z0-9_.-/]|i', '',
 $_GET['template']);
 var_dump($_GET['template']);die; // foobar
 }}}


 Platform is Apache 2.2 with php 5.2.6 on Leopard. I had ran into the issue
 in plugins in the past, but never in WP. Basically, it treats .-/ like a
 range, and changing it to ./- fixes the thing.

 The fix is trivial, and is attached.
