(shr-descend, shr-tag-a): Display dummy anchor characters as the

renders.  (Bug#40532)

search accordingly.

more of format-spec's supported text manipulation.
(format-spec): Autoload.  Allow optional argument to take on special
values 'ignore' and 'delete' for more control over what happens when
a replacement for a format specification isn't provided.  Bring back
proper support for a precision modifier similar to that of 'format'.

* lisp/battery.el (battery-format): Rewrite in terms of format-spec.
(battery-echo-area-format, battery-mode-line-format): Mention
support of format-spec syntax in docstrings.

* etc/NEWS: Announce removal of aliases obsolete since Emacs 24.3.

* lisp/net/dbus.el: Remove unneeded dependency on cl-lib.el.  Quote
function symbols as such.
(dbus-ignore-errors): Don't add macro name to font-lock keywords, as
emacs-lisp-mode now dynamically fontifies new macro definitions.
(dbus-event-error-hooks, dbus-call-method-non-blocking): Remove
aliases obsolete since Emacs 24.3.
(dbus-register-signal, dbus-escape-as-identifier): Simplify.  Use
