v2. Respect `erc-prompt-for-password'. Remove `run-at-time' hack from
regression fix.

I've forsaken the first part out of an abundance of caution. So this now
just prints a warning and proceeds with a non-TLS connection. If anyone
finds that unsatisfactory, please say something.

IOW, the de facto goal here is to make interactive `erc' a "universal"
entry point for both plain and TLS connections.

Subject: [PATCH 1/4] Fix default-port regression in erc-select-read-args
* lisp/erc/erc.el (erc--warn-unencrypted): New function, likely
temporary, to warn new users connecting interactively to the default
server, "irc.libara.chat", via the default non-TLS port, 6667.
(erc-select-read-args): Remove stray code from incomplete feature
introduced by bug#56514. Ensure connecting always works with default
port, which is non-TLS. Respect `erc-prompt-for-password' when user
pastes URL containing password component into "server" prompt. Maybe
add `erc--warn-unencrypted' as one-off hook for impending connection.
* test/lisp/erc/erc-tests.el (erc-select-read-args): Always expect
password prompt and sometimes a non-TLS port when `erc' called
interactively. (Bug#60428.)

Subject: [PATCH 2/4] [5.6] Be smarter about switching to TLS from M-x erc
* lisp/erc/erc.el (erc--warn-unencrypted): Remove newly unused
internal function.
(erc-select-read-args): Offer to use TLS when user runs M-x erc and
opts for default server and port or provides the well-known IANA TLS
port or enters an ircs:// URL at the server prompt. For the last two,
do this immediately instead of calling `erc-tls' interactively and
imposing a review of just-chosen values. Also remove error warnings
and ensure `erc-tls' still works by setting
`erc-server-connect-function' to `erc-open-tls-stream' when
appropriate. Include the word "URL" in server prompt.
(erc, erc-tls): Add internal keyword arguments for interactive use,
but don't make them colon-prefixed, i.e., `keywordp'.
* test/lisp/erc/erc-tests.el (erc-select-read-args): Modify return
values to expect additional `connect-function' keyword argument.

Subject: [PATCH 3/4] [5.6] Add display option for interactive ERC invocations
* lisp/erc/erc.el (erc-buffer-display, erc-receive-query-display):
Add aliases for `erc-join-buffer' and `erc-auto-query'.
(erc-interactive-display): Add new option to control display of server
buffers during interactive entry-point invocations.
(erc-select-read-args): Pass `erc-interactive-display' to entry
points.
(erc, erc-tls): Add interactive-only to control initial buffer
display.
* test/lisp/erc/erc-tests.el (erc-select-read-args): Expect
buffer-display values from `erc-interactive-display'. (Bug#60428.)

To reproduce from emacs -Q, do an M-x erc and accept the default offered
at every prompt. Assuming your IP is not blacklisted by Libera, you
should see a connection failure immediately because a TLS endpoint is
dialed but negotiation never occurs.
This all stems from a lapse in professionalism on my part: an
underrealized feature snuck in with the changes from bug#56514, but
missing logic made it impossible to connect using the default prompt
values, which should probably always succeed because some people don't
care about parameters and just want to get there somehow (so I'm told).
Alternatively, if a deliberate failure is indeed warranted (an arguably
valid position), the error message should at least explain as much.
FWIW, the missing feature was supposed to offer an interactive upgrade
to TLS upon detecting a user's intent to connect to the default server
and, on confirmation, adjust ERC's parameters on the fly. The proposed
patch abandons most of the envisioned niceties and instead employs a
hack to just force a non-local exit and schedule a call to `erc-tls'
when appropriate. It also instructs users to do that themselves in the
future (issue an M-x erc-tls, that is). Hopefully, this makes for an
acceptable compromise.
BTW, a POC patch set far more faithful to the original breadth of the
feature (and way less hacky) is also attached. Perhaps it'll inform
further exploration in this area down the road (but not for Emacs 29).
Thanks.
P.S. Shout out to the Libera users who brought this to my attention.

Subject: [PATCH 1/4] Fix default-port regression in erc-select-read-args
* lisp/erc/erc.el (erc-select-read-args): Fix incomplete feature
introduced by bug#56514. Ensure connecting always possible with
non-TLS default port, but offer upgrade.
* test/lisp/erc/erc-tests.el (erc-select-read-args): Expect a prompt
and possible `user-error' when calling `erc' interactively with all
default arguments.

Subject: [PATCH 2/4] [POC] Offer TLS by default for M-x erc
* lisp/erc/erc.el (erc-select-read-args): Offer to use TLS when user
runs M-x erc and opts for default server and port. But do this
immediately instead of calling `erc-tls' interactively and imposing a
review of just-chosen values. Also remove error warnings and ensure
`erc-tls' still works by setting `erc-server-connect-function' to
`erc-open-tls-stream' when appropriate.
(erc, erc-tls): Add internal keyword arguments for interactive use,
but don't make them colon-prefixed, i.e., `keywordp'.
* test/lisp/erc/erc-tests.el (erc-select-read-args): Modify return
values to expect additional `connect-function' keyword argument.

Subject: [PATCH 4/4] [POC] Optionally prompt for more ERC entry-point params
* doc/misc/erc.texi: Update statement about availability of user param
when entry points called interactively.
* lisp/erc/erc.el (erc-select-read-args): Allow optionally calling
entry points with a prefix arg to access params `user' and
`:full-name'.
(erc-tls): Update doc string.
* test/lisp/erc/erc-tests.el (erc-select-read-args): Add test for
extra args.
