Something smells rotten in redisplay

Something smells rotten in redisplay

[Juanma Barranquero]

The redisplay bug connected to setting `scroll-conservatively' to a
non-zero value is still there.

I'm now getting it while editing a HTML file with the standard
`html-mode' from sgml-mode.el. In some cases Emacs enters an (apparently
endless) loop while scrolling down. The backtrace from C-g says just:


Debugger entered--Lisp error: (quit)
  recursive-edit()
  byte-code("Æ\b!^[,HG^[(B ^[,HH	^[(B!^[,H\^[(Bn^[,C?
  debug(error (quit))



Also, while scrolling down sometimes the hollow cursor shape has been
partly drawn over the mode-line:

   --
  |XX|  This is the (partially shown) last line of the current buffer
--|  |----------------------------------------------------------------
  |  |  This is the mode-line
   --


The upper part of the cursor is filled, and the lower part is hollow.


                                                           /L/e/k/t/u

Seeing this reminds me of a question I have: Is that
backtrace representation of byte-code("...") really necessary that way.
The actual string is useless in most cases, you can't really copy
that and use it for something.  
COuldn't we either elide such byte-code strings, or replace them with
a human readable version of a byte-code string?
