Re: [T. V. Raman] read-only modes should be using buffer-disable-undo?

[T. V. Raman]

Modes that I've spotted so far where undo could be disabled:

Man-mode
w3-mode  (not yet part of emacs)

With respect to the aggregation of small chunks I do not believe I'm
seeing any buggy behavior;
however the recent updates in simple.el that cause the yes/no dialog 
to ask about discarding undo information does pop up in shell-mode --- 
I've had this happen during:

A) Compilation of alsa (a fairly large compile )
B) running yum update which produces lots of output
C) Compiling Emacs from CVS
