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

I run 21.3.50 from CVS, and recent updates to simple.el
produce a yes/no dialog when the undo information to save becomes
large; this pointed out an interesting place where Emacs libs could
be optimizing but apparently aren't -- namely, cases like man-mode.
There probably are other modes we should optimize in this way, once
the specific modes are identified. I did man-mode yesterday.
You could probably do something similar during the execution of a
shell command in shell-mode/comint-mode and friends; this would win in
the case of long running shell commands that produce lots of output a
small chunk at time.
The various undo-insert records could be optimized together, yes.
record_insert already tries to combine them. Do you know
for a fact that this optimization is not working in that case?]
