Attached is the updated patch. The most important difference compared
with the previous one is that this version allows to specify mailbox
URLs (pop://user:pass@server) even when emacs movemail is used.

One notice: rmail-insert-inbox-text contains branches that move
inbox contents directly using (copy-file) or (rename-file). Currently
these are not used, since the controlling variable `movemail' is set
unconditionally to `t'. Are there any plans to use these branches? Or
can I just remove them?
