This is with latest CVS emacs on GNU/Linux 2.4 (redhat 7.2)
with Xfree 4.(something) running under X:
Save this file in x.c:
- -------------------------------------------------
f()
{
switch (a)
{
case 1:
break;
case 1:
break;
}
}
- ------------------------------------------------
[Notice that the "break;" lines are indented by two TABs].
Start emacs -q and do C-x C-f x.c RET
Now move the cursor _below_ the space in "case 1:", ie.
case 1:
X break;
here....^
Hit TAB.
The screen now looks like (cursor is on the `b'):
case 1:
br ak;
?.......^
Doing C-l brings back the missing `e'.
My guess is that if the cursor was on a TAB, the position
occupied by that TAB will be left blank after redisplay.
To see this, indent the "break;" by "TAB SPACE TAB" and
put the cursor on the SPACE and press TAB => correct redisplay.
.. but there must be more to it than that.
I don't have time to investigate this further right now.

The Emacs/Guile plan has moved Emacs to the low end of my personal
priority list. I'll queue reports, but it's currently unlikely that
I'll work on them.

Basing Emacs on Guile, and what follows from it.

Yeah, but that's been a vague concept since the dawn of time; your
message implies that there's actually something happening...

I'll let Richard answer what the state of affairs is. I was referring
to something on emacs-hackers and later in private mail. Obviously,
I've made my personal decision.

If moving to Guile means we lose Gerd's help, then I'm against moving
to Guile as a matter of practice.
I'm serious.

I see that what I wrote can be misunderstood, for example as simply
being opposed to Scheme or Guile as a matter of principle. So please
let me clarify.
There are technical reasons for being against a reimplementation of
ELisp in Guile, or for making Guile Emacs' principal extension
language. These issues can theoretically be solved with enough
effort. I personally think there's too much effort and risk involved;
others might find that debatable or irrelevant in the bigger GNU
picture. I also don't like the way this crept up again, but this is a
completely different story which I won't belabor here. Anyway,
although I'm against such a move, the reason Emacs has lost priority
for me _today_ is this, in short:
The "new" redisplay is anything but new for me. Today, working on it
is for me a mixture of incredibly boring and inherently and constantly
complex that makes it essentially a pain in the neck. That's not a
good motivation, of course, and it's getting worse.
In the past, it helped me to find something else in Emacs to work on,
and do a bit there, a bit in redisplay etc. Lately, the only "else"
part remaining that might have interested me enough was the ELisp
interpreter. But work there doesn't make sense when the ELisp
implementation is anyway replaced, and something else becomes the
primary extension language. (What makes sense is working on Guile
instead (not saying that I'll do that.))
(I've been looking for other projects that might play that role, but
there's currently nothing.)
So, no motivation => low priority.

guile would benefit greatly from your involvement.
i'm sure emacs would benefit indirectly but still substantially.

Won't you please at least fix the bugs in the display code that you
wrote?

I'm afraid kind of appealing to my sense of duty has no effect at
present, because, after having invested that vast amount of nerves
(you know what I mean), time, and effectively money, I don't think
there's a moral obligation left on my side.
