Subject: PATCH: Improved _mailboxes
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii

This works pretty well, following Sven's most recent patches to _multi_parts.
It now can handle mailboxes for elm, mail, mh, mutt, pine, and zmail.

Things I like it to do that it doesn't yet:

(1) The default style should be to make the all-files group be alternate
    completions, i.e., not shown unless the -default- group is empty.

(2) The all-files group for pine (currently commented out) should contain
    only full paths, not relative ones.  How does one accomplish that?

(3) I'm sometimes offered a blank completion -- an empty slot at the top
    of the list of all completions.  I don't know where that comes from;
    it shouldn't be there.  Quoting problem somewhere?

And of course, I haven't yet written any actual completion functions to
call this one; it's used only from _mutt, so far.
