Subject: 24.4; F4 may be inserted into emacs macro when blink-matching-paren
 is enabled
Date: Mon, 27 Oct 2014 11:28:38 +0100

Starting from emacs -Q:
*  Open an html file (e.g. /tmp/foo.html)
* Type <b
* Start a macro with F3
* Quickly enter > followed by F4
* M-x edit-last-kbd-macro now shows that F4 has been inserted into the
macro.

I believe that this bug is, in some way, caused by 
blink-matching-paren.
F4 only seems to be entered into the macro when the preceding "<" is
highlighted.

Also, I cannot reproduce the bug when setting blink-matching-paren to
nil.

I originally saw this problem in 24.3, but I have just compiled 24.4
to confirm that the bug is still present there.

Hello,

I have just tried to reproduce it on GNU Emacs 25.1.50.4 (commit
f182640), and could not.  Could you confirm that this is no longer
a problem?  (If you do not want to compile Emacs from the Git repo,
maybe try the latest pretest, see
http://alpha.gnu.org/gnu/emacs/pretest/)

Best,

More information was requested, but none was given within close to 4
years, so I'm closing this bug report.  If this is still an issue,
please reopen the bug report.
