Some things I noticed while writing a quick how-to on
"lei ls-mail-source" and .onion usage in
https://public-inbox.org/meta/20210915230605.GA22173@dcvr/

We can't easily use torsocks, here, so try to be helpful
when it comes to proxy support.

Otherwise, public-inbox-imapd will emit mailboxes in random
order (as IMAP servers do not need to guarantee any sort of
ordering).  We'll take into account numeric slice numbers
generated by -imapd if they exist, so slice "80" doesn't show up
next to "8".

While RFC 3501 doesn't require LIST responses be sorted,
it makes reading protocol dumps easier and we memoize it
once per-refresh, so it shouldn't be too expensive even
with thousands of folders.
