Possibly uninitialized variables

I am considering adding to your module (I maintain a multi-lingual WordPress plugin, and would like to use your module, slightly modified, to import from a WP installation that uses it. I'm not sure whether you want this addition to your module, but if/when I get it working, I'll at least file an issue and attach a patch so that you can decide.)

Anyway, that aside, I started by doing a CVS checkout on the 6.x-2.x branch, and I opened wordpress_import.module in my Eclipse PHP editor.

It is complaining about uninitialized variables in two places:
$base_path at line 205 in wordpress_import_form_file()
$user at line 641 in wordpress_import_form_newusers_validate()

I am not sure if these are real errors or not (still getting used to the module code), but I thought I would at least let you know.

Great module, by the way -- I found it to be easy to use and it worked fine for me. Thanks!
