Move the warning about unused return values from calls to
side-effect-free functions from the source-level optimiser to the code
generator, where it can be unified with the special-purpose warning
about unused values from `mapcar`. This change also cures spurious
duplicate warnings about the same code, makes the warnings amenable to
suppression through `with-suppressed-warnings`, and now warns about
some unused values that weren't caught before.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker):
Move warning away from here.
* lisp/emacs-lisp/byte-run.el (with-suppressed-warnings):
* lisp/emacs-lisp/bytecomp.el (byte-compile-warnings):
Doc string updates.
(byte-compile-form): Put the new warnings here.
(byte-compile-normal-call): Move mapcar warning away from here.
* lisp/emacs-lisp/bytecomp.el (byte-compile-ignore):
Compile args to `ignore` for value to avoid unused-value warnings, and
then discard the generated values immediately thereafter. Mostly this
does not affect the generated code but in rare cases it might result
in slightly worse code.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-test--with-suppressed-warnings): Adapt test.
* lisp/ibuf-ext.el (ibuffer-diff-with-file): Link to diff-command in
docstring. Make Diff buffer read-only from outset and inhibit as
needed to avoid surprises. Check whether diff-command
supports --label. Leave point at BOB and clean up any excess
newline inserted by ibuffer-diff-buffer-with-file-1. Prefer
pop-to-buffer-same-window over switch-to-buffer.
(ibuffer-diff-buffer-with-file-1): Add docstring. Remove unused
unwind-protect and copypasta from diff-no-select (bug#62599). Use
diff-file-local-copy, string-join, and redisplay in place of
analogues. Condition --label use on availability, and label buffers
consistently with diff-no-select. Leave empty line between runs.
Let diff-sentinel delete temporary files. Leave point at EOB for
next run.
Even though Eglot is a :core ELPA package and as such is on a
different release cycle than Emacs proper, the version strings used in
'defcustom' and 'make-obsolete' must still follow the numeric format.
* lisp/progmodes/eglot.el (eglot-report-progress): Adjust :version.

(eglot--managed-mode-hook): Update "obsolete" spec.

Also check for text-property-search-forward before using it, so we
won't break on Emacs 26.3. At this point, better start relying on
compat.el, I guess.
* lisp/progmodes/eglot.el (eglot--format-markup): Check for
text-property-search-forward.
Although in most situations this doesn't error, it's only because of
the very wide binding of inhibit-read-only in jsonrpc--process-filter.
That binding will soon be narrowed, so better not rely on it.

The functionality under test in eglot.el is exactly the same, but use
the clangd server only, as that is used in more tests, and it is much
easier to check if it misbehaves or not.
Tests pass with clangd version 15.

Most newer servers return a vector of 'DocumentSymbol' as a response
to 'textDocument/documentSymbol'. It's not worth trying to dumb this
down to imenu format of 'SymbolInformation' vectors.
This lays groundwork for the forthcoming "breadcrumb" feature of
bug#58431.
* lisp/progmodes/eglot.el
(eglot--imenu-SymbolInformation, eglot--imenu-DocumentSymbol): New
helpers.
(eglot-imenu): Rework.
