Hi,
I am using 21.5.2 CVS (main trunk). Is the following behavior
correct?
(int-to-char -51)
=> ?\^^M
If so, we should modify mule-packages/egg-its/egg.el not to use
negative numbers for `int-to-char'. Because of this behavior,
Egg often hangs up when I mis-type (e.g. C--) in the fence-mode.
Here is a patch for egg.el:
2001-08-21 Katsumi Yamaoka <yamaoka(a)jpl.org>
* egg.el (egg-read-event): Don't specify a negative number to
`int-to-char'.

(event-to-character event)))
(setq unread-command-events (list event))))
(setq unread-command-events (list event)))

This "sounds" OK to me. Could somebody more knowledgeable than I
please comment.

It's a bug in int-to-char:
`int-to-char' is a built-in function
(int-to-char INTEGER)
Documentation:
Convert integer INTEGER into the equivalent character.
Not all integers correspond to valid characters; use `char-int-p' to
determine whether this is the case. If the integer cannot be converted,
nil is returned.
21.4.4 returns nil in Yamaoka-san's example.
What does EGG do with nil? If its behavior is sensible, then we should
just fix 21.5.

It's a bug in int-to-char:
[...]
21.4.4 returns nil in Yamaoka-san's example.
Yes. It occurs only in latest 21.5.2.
What does EGG do with nil?
Nil for negative arg is OK, if anything, it seems that Jareth
uses that behavior deliberately in `egg-read-event'.
If its behavior is sensible, then we should just fix 21.5.
I hope so. Thanks.

VETO
The bug is in buffer.h, not in EGG. Patch forthcoming.
