bug#946: 23.0.60; html-mode regression ('' within a table)

[Allan Gottlieb <gottlieb@nyu.edu>]

This mail is being sent from a different system (ajglap) from the one
on which the bug occurs (allan).  I did run report-emacs-bug on the
system with the bug and what follows is the
*mail to emacs-pretest-bug@gnu.org* buffer.

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

1. Create the following 3 line file /tmp/x.html

<table>
  <tr><td>'9'</td></tr>
</table>

2. invoke emacs -Q /tmp/x.html

3. C-x h   to mark the buffer

4. C-M-\   to indent the buffer

5. The indentation is not changed (correct), but the message
   Unclosed tag <>
   is generated (wrong).

6. This does not occur with emacs 22.2 and does not occur if
   the three characters '9' are replaced with 9 or '9 but does occur if
   they are replaced with 9'

Thank you for emacs, which I have used for 20+ years.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
