Fix recursively scanning Maildir folders

Browse Source 
Commit 1754bf4110 introduced a blunder:

-        for dirname in os.listdir(toppath) + ['.']:
+        for dirname in os.listdir(toppath) + [toppath]:
...
-            if self.getsep() == '/' and dirname != '.':
+            if self.getsep() == '/' and dirname:

This change was plainly wrong and would never have worked, so this
commit reverts above bit. While touching the function, some minor code
documentation, cleanup and limiting line length to 80 chars.
