bug#49332: No mention in manual of how to make text blink

[積丹尼 Dan Jacobson]

In the emacs manual there is plenty of mention of how to make the cursor blink.
Alas, e.g.,
(info "(emacs) Face Customization") and (info "(emacs) Faces")
neglect mentioning how to make text blink.
I recall even a VT100 could be made to make text blink.

There are VT codes for blinking text, but documenting that would be out
of scope for the Emacs manual.  In Emacs, if you want to make text
blink, you have to write code to blink the text (with timers and stuff),
and that's also out of scope for this manual entry.

So I'm closing this bug report.

Actually all that is needed is the face for the cursor mentioned in
frame.el just needs to be shared with the rest of Emacs.

  You can also set the text cursor color, for all frames, by
  customizing the `cursor' face."

I.e., if other faces could also use the cursor's blinking face,
then I could even add blinking in addition to just
(custom-set-faces'(message-header-cc((t(:foreground "white" :bold t :background "tomato")))))
(custom-set-faces'(gnus-header-cc((t(:foreground "white" :bold t :background "tomato")))))
in an extra effort to make it clear that I was about to send a mail to
more people than I might have thought I was.
And more people were reading the message I was reading too.

No, because the way Emacs makes the cursor blink has nothing to do
with faces.  See blink-cursor-mode, which is a separate feature,
orthogonal with faces.

There's no such thing as "cursor's blinking face" in Emacs.
