bug#58840: 29.0.50; Make scheduled reconnects friendlier in ERC

[J.P.]

Tags: patch

Hi people,

IRC connections die for a good many reasons. But ERC currently lacks a
decent means of staying abreast of scheduled reconnection attempts
(which has reportedly confused and frustrated newer users). And trying
to cancel an attempt (possibly to clear the way for reconnecting
manually) is likewise inconvenient.

The patch below tries to improve the situation somewhat. For starters,
it borrows a "slash" command, /rmreconns, from Irssi and also introduces
a slight variant, /rmreconn (without the "s"). These simply cancel one
or all pending reconnect attempts. Suggestions for alternate names
and/or aliases welcome.

Also included is a tweak to /reconnect to ensure it always cancels an
active timer before connecting. This should allow the lazy/impatient
among us to expedite proceedings in a single command. Also added is a
new "reconnecting in <N>s" mode-line indicator as well as a printed
reminder in the server buffer of the configured wait time when a timer
is first set. Note that the mode line doesn't update automatically
(there's no periodic countdown, IOW), but it *does* update on user
input, e.g., when you move point around. (Hopefully that's sufficient.)

Please offer feedback if you care about this feature. It's not a
priority for me, so if anyone wants this in ERC 5.5 and Emacs 29, please
make that known.

Thanks,
J.P.

P.S. This patch assumes bug#56340's changes have been applied; expect
some benign complaints from the compiler if they haven't.
