bug#18130: rmail: allow for imaps proto

Currently mailutils movemail works with gmail imap using this:

movemail 'imaps://carlosjosepita%40gmail.com:XXXX@imap.gmail.com/INBOX'
RMAIL

but not this:

movemail --tls 'imap://carlosjosepita%40gmail.com:X
XXX@imap.gmail.com:993/INBOX' RMAIL

I wouldn't be difficult to support imaps in rmail, as it's just forwarding
the request to movemail, which already supports it. This way it would be
possible to use gmail imap in rmail.

bug#18130: Acknowledgement (rmail: allow for imaps proto)

[Carlos Pita]

Same for pop / pops:

Error:

[loscar@localhost ~]$ movemail --tls
'pop://carlosjosepita%40gmail.com:crapulario@pop.gmail.com:995' test3
movemail: mailbox
`pop://carlosjosepita%40gmail.com:***@pop.gmail.com:995': cannot open:
Input/output error

Ok:

[loscar@localhost ~]$ movemail
'pops://carlosjosepita%40gmail.com:crapulario@pop.gmail.com:995' test3

Currently there's no way to use rmail with gmail via movemail.

bug#18130: rmail: allow for imaps proto

The problem seems more general, indeed. Non recognized protocols are
taken to be filenames and expanded, as in:

maildir:/home/loscar/Mail/INBOX
->
/home/loscar/maildir:/home/loscar/Mail/INBOX

mailutils movemail is pretty smart, but rmail is dumbing it down. I
think a more transparent delegation to the mailutils workhorse is in
order.

I've been doing some debugging. The problem is in
rmail-insert-inbox-text, which calls expand-file-name. I'm not sure
whether you intend to support anything more than mbox, pop and imap or
not, but then this documentation:

https://www.gnu.org/software/emacs/manual/html_node/emacs/Movemail.html#Movemail

is very misleading in at least two ways:

* It doesn't mention pops and imaps at all.

* It suggests that a larger number of protocols could be used with
mailutils movemail.

So there's a bug anyway:

* Either the documentation should clearly state that only "pop:...",
"imap:..." and "/path/...." specifications are supported, despite the
more powerful capabilities of mailutils movemail

* Or the other protocols supported by mailutils movemail should be
supported by rmail also. In this case, something has to be done before
the filename logic in rmail-insert-inbox-text, which will be broken in
many ways because of the protocol prefix.
