Re: [bug-mailutils] Should (mu-mailbox-open "file:///FOO" "r") work on a random mh dir?

It seems I've forgotten to document it. By default Scheme interface
registers only unix mailbox handler, all the rest you need to request
explicitely. If you need only "mh" handler, calling

(mu-register-format "mh")

will do.

The function takes arbitrary number of arguments, so you can register
several handlers in one go:

(mu-register-format "mh" "maildir" "imap")

Calling it without arguments registers all available mailutils format
handlers.

I'll update the docs. In the meantime, you can find all the docstrings
in guile-procedures.txt, installed in the mailutils modules directory.
