Bug: XEmacs doesn’t display Control-characters correctly anymore

[Mike FABIAN]

For details see

    http://bugzilla.novell.com/show_bug.cgi?id=354705

XEmacs version is:

(emacs-version)
"XEmacs 21.5  (beta28) \"fuki\" (+CVS-20071205) [Lucid] (x86_64-suse-linux, Mule) of Mon Jan 14 2008 on magellan"

Problem description:

If one inserts a control character like Control-L or Control-M
in to an XEmacs buffer, these characters used to be displayed
as ^L and ^M respectively (One can input a Control-L by typing
C-q C-l).

Now, Control-L is just displayed as 'L', without the '^' in front
which makes it very hard to see. If there is a string which contained
such a Control character it used to look like for example

    hello^Lworld

but now it looks like

    helloLworld

When moving the cursor over this string, the cursor used to
sit on the ^ when reaching the Control-L, then jump to the
next character (here 'w') when moving it right.

Now, the cursor disappears completely when it reaches the Control-L
and appears again when the 'w' is reached.

This is very confusing and annoying.
