Improve correctness of Eshell sub-forms

This makes sure that we treat Eshell sub-forms (whether Lisp or command
forms) as values when appropriate, or as regular invocations.  This

Simplify creation of Eshell command forms

Previously, Eshell over-aggressively converted subcommands, which forced

Crystallize erc-nicks-track-faces behavior

* 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.

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.

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.

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)

Fix c-ts-mode indentation for initializer lists (bug#73661)

The intentation behavior differed between c-mode/c++-mode
and *-ts-mode for initializer lists where the first element was
not at beginning-of-line.  The anchor-prev-sibling function gave
up and returned nil, but it should (probably) anchor on the
first element in the initializer list, such as this:

return { v1, v2, ...,
         y1, y2, ... };

c-ts-mode behaved better and figured out how to align, but I
added a test for a similar compound literal to prevent
regressions.
