Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
this seems to be a sure bug.
In html-mode. If you have this:
<p>some'</p>
and your cursor is at the beginning of line, then press C-c C-d
(sgml-delete-tag), it'll also delete the apostrophe.
This is “GNU Emacs 23.2.1 (i386-mingw-nt6.0.6002) of 2010-05-08 on G41R2F1”

Hi,
can confirm this bug.
GNU Emacs 23.2.94.1 (i686-pc-linux-gnu, GTK+ Version 2.18.6) of 2011-02-25
Error is in backward-prefix-chars, ie. in syntax.c AFAIS.
line 2855
while (!char_quoted (pos, pos_byte)
/* Previous statement updates syntax table. */
&& ((c = FETCH_CHAR_AS_MULTIBYTE (pos_byte), SYNTAX (c) == Squote)
|| SYNTAX_PREFIX (c)))
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
may that `or' SYNTAX_PREFIX above?

Why would you think so? I'd rather say that the error is that ' in
html-mode buffers should not have prefix syntax.

Indeed, thanks
couldn't get the syntax properly, as my report function in use failed.
with point at opening lesser-angle at closing tag
(syntax-after (1- (point)))
returns (1048578)
while word chars before return
(2)
checked with
(defun syntax-bfpt ()
(interactive)
(let ((stax (syntax-after (1- (point)))))
(when (interactive-p)
(message (format "%s" stax)))
stax))
