Remember: for most options, compadd uses the first occurrence if they
are given more than once (the exception is -M -- all of them are
used).

In other words: the arguments given to _mailboxes override the
defaults it builds itself.

Not really. _files parses its arguments and takes all interesting
options to give it to _path_files. Some time ago it just did the same
as _mailboxes, but with the appearence of tags _files had to learn to
modify or ignore some of the things it got (e.g. a -g option).

First, I would get rid of the (expansion of) ~/Mail at the beginning
of all the strings in the cache. And then just use _multi_parts like
_tar does. (I haven't really looked at how the cache looks like
because I use a self-written mail reader, but I guess it just contains 
filenames and stuff, right?)


Some doc fixes.
