password.  And when `erc-prompt-for-password' was nil and

their names are unique.  Register these on all three of ERC's
kill-buffer hooks because an orphaned target buffer is enough to keep
its session alive.
(erc-networks-rename-surviving-target-buffer): Add new function that
renames a target buffer when it becomes the sole bearer of a name
based on a target that has become unique across all sessions and, in
most cases, all networks.  IOW, remove the @NETWORK-ID suffix from the
last remaining channel or query buffer after its namesakes have all
been killed off.  Register this function with ERC's target-related

Return sentinel on failure.  Expect `erc-server-announced-name' to be
set, and signal when it's not.
(erc-networks--name-missing-sentinel): Value returned when new
function `erc-networks--determine' fails to find network name.  The
rationale for not making this customizable is that the value signifies
the pathological case where a user of an uncommon IRC setup has not
yet set a mapping from announced- to network name.  And the chances of
there being multiple unknown networks is low.
(erc-set-network-name, erc-networks--set-name): Deprecate former and
partially replace with latter.  Ding with helpful message, and don't
set `erc-network' when network name is not found.

existing target buffers that ought to be owned by the new server
process.  The second grabs buffer text from an old, dead server buffer

current, replacement server buffer.  The other two massage the IDs of
related sessions, possibly renaming them as well.  They may also
uniquify the current session's network ID.
(erc-networks--init-identity): Add new function to perform one-time
session-related setup.  This could be combined with
`erc-set-network-name'.
(erc-networks--rename-server-buffer): Add new function to replace
`erc-unset-network-name' as default `erc-disconnected-hook' member;

regression involving unwanted automatic reassociation of channel
buffers during joins, which arrived in ERC 5.4 and effectively
inverted the meaning of this variable, when nil, for channel buffers,
all without accompanying documentation or announcement.
(erc-generate-new-buffer-name): Replace current policy of appending a
slash and the invocation host name.  Favor instead temporary names for
server buffers and network-based uniquifying suffixes for channels and
query buffers.  Fall back to the TCP host:port<n> convention when
necessary.  Accept additional optional params after the others.
(erc-get-buffer-create): Don't generate a new name when reconnecting,
just return the same buffer.  `erc-open' starts from a clean slate
anyway, so this just keeps things simple.  Also add optional params.

connections and otherwise copy it over.  As part of the push to recast
erc-networks.el as an essential library, set `erc-network' explicitly,
when known, rather than via hooks.
(erc, erc-tls): Add new ID keyword parameter and pass it to
`erc-open'.
(erc-log-irc-protocol): Use `erc--network-id' instead of the function
`erc-network' to determine preferred peer name.
(erc-format-target-and/or-network): This is called frequently from
