inline base64-encoded binaries in the Message buffers.

subr-x.el.
(format-spec-make): Clarify docstring.
(format-spec--parse-modifiers): Rename to...

(format-spec--do-flags): ...this new helper function which performs
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'.

(message-sendmail-envelope-from): Use it.
* lisp/mail/emacsbug.el (report-emacs-bug): Use it.
* lisp/gnus/message.el (message-widen-and-recenter): New command
to ensure that we show most of the headers (bug#23252).

* message.el (message-font-lock-keywords)
(message-font-lock-make-cited-text-matcher): Add support for
different faces for different citation levels. The faces are
defined in the faces named `message-cited-text-N': N of the
Mth citation level will be M mod 4.
(message-cited-text-1, message-cited-text-2)
(message-cited-text-3, message-cited-text-4): Add customization
for the faces of 4 different citation level. In the future, the
number of faces may increase, as the code is flexible enough to
automatically deal with that.

determination of cite levels given the prefix of the cited text
(bug#25022).
* lisp/gnus/gnus-msg.el (gnus-inews-do-gcc): Use it to avoid
