} This is exactly what I am trying to teach zsh-3.1.6.pws16 to do.
The follow only sort of accomplishes it. I now get:
zagzig[166] mutt -f +z<TAB>
zagzig[166] mutt -f /home/schaefer/Mail/z<TAB>
/home/schaefer/Mail/zanshin /home/schaefer/Mail/zsh-maintenance
/home/schaefer/Mail/zsh
<BEEP>
That is, the first TAB replaces the + with the $maildirectory path, the
second TAB lists the completions.
There has to be a better way.
One thing that makes this difficult is that _path_files does not accept
the -i option of compadd, only the -P option. However, even calling
compadd -i + -f -W ~/Mail
directly does not accomplish what I expected it to. Is this a bug, or am
I missing something? What IS the compadd equivalent of
compctl -x 's[+] c[-1,-f],s[-f+]' -W ~/Mail -f ...

1) Depending of the setting of the group-name style you may have gotten
different names.
2) Yes, that's ok. The _description in _mailboxes sets up a default
description that may be overridden by a calling function.
3) Depending on the implementors preferences, he may or may not change
the '-f+:mailbox:_mailboxes' to '-f+:mailbox: _mailboxes', which will
make _arguments *not* give a description to _mailboxes (i.e., then you
only get the second one).

All completion I can think of are written so that they work nicely
when PREFIX/IPREFIX (and SUFFIX/ISUFFIX) are set up appropriately.

-i just *adds* some string to IPREFIX. It is really only useful when
used with -U, i.e. by functions that have to do all the matching
themselves (because then IPREFIX isn't used by the completion code and
-i can be used to tell it about an ignored prefix).
So, the right way to do the same as that compctl would be:
if compset -P '+|-f+' || [[ $words[CURRENT-1] = -f ]]; then
_files -W ~/Mail
else
...
fi
where the compset sets up PREFIX/IPREFIX for us.
