This fixes bug #59038. The infinite loop occurred with a buffer containing
Base-64 encoded text rather than appropriate C Mode text.
* lisp/progmodes/cc-engine.el (c-update-brace-stack): Don't execute
c-beginning-of-current-token unless the previous c-syntactic-re-search-forward
has succeeded at least once.
This will allow possible future extensions to customize Double (HiDPI).
(tab-bar-fixed-width-min): Change :type from cons to list.
(tab-bar-fixed-width): Use the list instead of cons.
* lisp/erc/erc-dcc.el (pcomplete/erc-mode/DCC): Add /DCC GET switches.
This is unfinished business from bug#54458.
* test/lisp/erc/erc-dcc-tests.el (erc-dcc-tests--pcomplete-common,
pcomplete/erc-mode/DCC--get-basic, pcomplete/erc-mode/DCC--get-1flag,
pcomplete/erc-mode/DCC--get-2flags,
pcomplete/erc-mode/DCC--get-2flags-reverse): Add helper and tests for
completing /DCC GET switches.
* lisp/progmodes/cpp.el (cpp-highlight-buffer): Use progress
reporter.
(cpp-progress-time, cpp-progress-message): Make obsolete in favor
of 'make-progress-reporter'.
(cpp-message-min-time-interval): Doc fix.
* doc/emacs/package.texi: Expand documentation and give example.
* etc/NEWS: Mention 'package-vc-selected-packages'.
* lisp/emacs-lisp/package-vc.el (package-vc--select-packages): Remove
function.
(package-vc-ensure-packages): Add function based on
'package-vc--select-packages'.
(package-vc-selected-packages): Call 'package-vc-ensure-packages' from
custom setter.
(tab-bar-fixed-width-max): New user option.
(tab-bar-fixed-width-min): New variable.
(tab-bar-fixed-width-faces): New variable.
(tab-bar--fixed-width-hash): New function.
(tab-bar-make-keymap-1): Use 'tab-bar-fixed-width'.

* lisp/eshell/esh-util.el (eshell-stringify): Use 'string-trim-right'
instead of stripping the last character of the result of
'pp-to-string' (bug#58810).
* test/lisp/eshell/esh-util-tests.el: New file.
