Re: [PATCH v3] Add more methods to gdb.Progspace

LGTM, I just noted some minor comments.

I wish there was more consistency in how the methods are documented (in the
progspace_object_methods array), but that should be another patch.

Perhaps this should say gdb.current_progspace().find_pc_line(pc) ?

I know this is pre-existing code, but it could use Py_RETURN_NONE, then
we can get rid of the str_obj variable.
