bug#5380: Problem with command sgml-name-8bit-mode in GNU emacs 23.1

[Volker Kiefel]

Hello, dear maintainers of emacs and sgml-mode.el,

as a regular user of the html-mode of emacs I encountered a
problem with the function ``sgml-name-8bit-mode'', (menu option
(SGML/Toggle 8 bit insertion), as I changed to v23.1 of GNU
emacs. The problem encountered on the precompiled win32 version
and on the version in Linux compiled by myself.

After switching on the ``sgml name entity mode'' typing an umlaut
character like ä (a umlaut) now no more (as in previous emacs
versions and as expected) produces ``ä'' but ``\344''.

I hope that the problem can be fixed.

With kind regards
