(erc--querypoll-target-in-chan-p, erc--querypoll-get-length)
(erc--querypoll-get-next): Move to new file erc-notify-tests.el.
* test/lisp/erc/erc-notify-tests.el: New file.  The `querypoll' module
was first introduced as part of bug#70928 in ERC 5.6.

* test/lisp/erc/resources/erc-d/erc-d-i.el: Require `subr-x'.
(erc-d-i--parse-message): Populate `contents' slot when lone trailing
arg lacks a preceding colon.
* test/lisp/erc/resources/erc-d/erc-d-tests.el (erc-d-i--parse-message):
Fix expected result.
(erc-d-i--parse-message/privmsg): New test.

* doc/misc/erc.texi (Sample Configuration): Remove `erc-modules' from
the `:custom' section of the `use-package' declaration for feature `erc'
because its presence there depends on `:defer' being non-nil, and this
configuration is supposed to be `:defer' agnostic.  This reverts part of
3f1ce47f "; Add face customization to ERC's sample config".
* etc/ERC-NEWS: Mention `erc-modules' no longer being autoloaded.
* lisp/erc/erc-match.el (erc-text-matched-hooks): Explain expected
format of non-NUH matches.
* test/lisp/erc/erc-match-tests.el (test/lisp/erc/erc-match-tests.el):
Inhibit messages when running non-interactively.

* lisp/erc/erc-match.el (erc-pal-highlight-type)
(erc-fool-highlight-type, erc-dangerous-host-highlight-type): Clarify
some areas in doc strings.
* test/lisp/erc/erc-match-tests.el: Require `erc-test-common' library.

* etc/ERC-NEWS: Mention changes to `erc-track-faces-normal-list' and
`erc-track-faces-priority-list'.  Also mention new choice variant for
option `erc-nicks-track-faces', although that's arguably just a bug fix
because it makes good on previously unrealized behavior implied by the
doc strings.
* lisp/erc/erc-nicks.el (erc-nicks-skip-faces): Remove faces applied by
the `match' module, namely, `erc-current-nick-face', `erc-pal-face', and
`erc-fool-face'.  That module runs its hooks after `button' on
`erc-insert-modify-hook', and because `nicks' piggybacks on `button', it
can never encounter those faces while assaying.
(erc-nicks-track-faces): Update doc, and introduce new `t' value choice.
(erc-nicks-mode, erc-nicks-disable): Update removals from
`erc-track--alt-normals-function' to reflect recent renamings.
(erc-nicks--reject-uninterned-faces): Use helper.
(erc-nicks--oursp, erc-nicks--ours-p): Rename former to latter to
respect project style guidelines regarding predicates.
(erc-nicks-track-normal-max-rank): New variable.
(erc-nicks--check-normals, erc-nicks--assess-track-faces): Rename former
to latter, and change purpose to checking for "normals" membership,
ranks position, and incumbent face ownership.  Remove unused CONTENDERS
parameter.  Additionally, change behavior to consider replacing the
current mode-line face when it's not `nicks' owned if it's explicitly
ranked lower than `erc-default-face'.
(erc-nicks--track-prioritize, erc-nicks--track-always): New
complementary functions implementing the t and `prioritize' variants of
`erc-nicks-track-faces'.  Both make use of the factored-out
`erc-nicks--check-normals' logic.
(erc-nicks--setup-track-integration): Add `erc-nicks--track-always' to
`erc-track--alt-normals-function' when `erc-track-normal-faces' is t.
* lisp/erc/erc-track.el (erc-track--massage-nick-button-faces): Change
type of symbol property `erc-track--obsolete-faces' for options
`erc-track-faces-priority-list' and friends from a boolean to an alist.
(erc-track-faces-priority-list): Add new face for buttonized speakers.
(erc-track-faces-normal-list): Add new face for buttonized speakers.
Also add `erc-notice-face'.
(erc-track--priority-faces): New local variable to cache ranked faces
and complement `erc-track--normal-faces'.
(erc-track--setup): Initialize new `erc-track--priority-faces' variable,
and refactor.
(erc-track--alt-normals-function): Doc.
(erc-track--select-mode-line-face): Update expected type of `ranks'
parameter.
(erc-track-modified-channels): Fix wrong-type bug occurring when
`erc-track-ignore-normal-contenders-p' and
`erc-track-priority-faces-only' are both non-nil.  Also fix subtle
compatibility oversight regarding an empty face list returned by
`erc-track--collect-faces-in'.
* test/lisp/erc/erc-nicks-tests.el: Load helpers and fixtures library.
(erc-nicks-tests--track-faces): New function.
(erc-nicks-track-faces/prioritize, erc-nicks-track-faces/defer)
(erc-nicks-track-faces/nil, erc-nicks-track-faces/t): New tests.

parameter.

(erc-tests-common-track-modified-channels-sans-setup): New functions.

* etc/ERC-NEWS: Announce removal of troublesome key binding first
introduced in ERC 5.6 as part of the `erc-fill-wrap' module.
* lisp/erc/erc-fill.el (erc-fill-wrap-mode-map): Remove key binding for
`erc-fill-wrap-cycle-visual-movement'.
* test/lisp/erc/erc-fill-tests.el (erc-fill-wrap-visual-keys--body)
(erc-fill-wrap-visual-keys--prompt): Replace "C-c a" key simulations.

* lisp/erc/erc-nicks.el (erc-nicks-mode, erc-nicks-enable)
(erc-nicks-disable): Use correct name for `track' module hook.
(erc-nicks--check-normals): Remove falsity from doc string.
* lisp/erc/erc-track.el (erc-make-mode-line-buffer-name): Don't error
when optional COUNT is nil.
(erc-track-modified-channels): Use new name for preferred face-finding
function.
(erc-track--get-faces-in-current-message, erc-track--collect-faces-in):
Rename former to latter to better reflect expanded utility, which now
includes spanning gaps, including newlines and indentation that may be
lacking in face-related properties.
* test/lisp/erc/erc-track-tests.el (erc-track--collect-faces-in): New
test.  (Bug#73443)

* etc/ERC-NEWS: Entry mentioning `erc-keep-place-indicator-truncation'.
* lisp/erc/erc-goodies.el (erc-keep-place-indicator-truncation): New
option.  Something like this should have accompanied the module's
introduction.
(erc-keep-place-indicator-mode, erc-keep-place-indicator-enable)
(erc-keep-place-indicator-disable): Arrange to take necessary measures
to avoid losing the indicator on `erc--clear-function'.  This module was
first introduced by bug#59943.
(erc--keep-place-move-hook): New variable.
(erc--keep-place-indicator-adjust-on-clear): New function.
(erc-keep-place-move): Try to ensure the overlay resides at the
beginning of a message.  Run hook `erc--keep-place-move-hook'.
* test/lisp/erc/erc-scenarios-keep-place-indicator-trunc.el: New file.
* test/lisp/erc/erc-scenarios-keep-place-indicator.el
(erc-scenarios-keep-place-indicator--follow): Fix missing test
description.  (Bug#72736)
