"if i.url" would be sufficient. I think it's fine to assume '' and None has the
same behavior?

For instance in run() at line 348, it uses if run_scm and self.parsed_url so ''
will have the same effect as None.

I'm not 100% sure though because LateOverride() has a different code path
depending if the url is a string or a None object. I guess if url == '', it's
just currently broken. In any case to stay safe it'd drop the "!= None".

       for entry, prev_url in self._ReadEntries().iteritems():
         if not prev_url:
           # entry must have been overridden via .gclient custom_deps
