This pertains to Gnuemacs.

Often, I would like to 'chunk' a large group of changes as a single 'undo'
action. E.g. if I replace-regexp several lines, I'd like to be able to
'undo' the lot of them, not each one.

I've read the docs concerning undo-boundry, but the problem is that I can't
over-ride the undo-boundries created by other functions.

While it might be possible to bind a null function to the undo-boundry
label, this doesn't work for built-in commands.

Does anyone have a command similar to what I've described? Any clues on how
to do it? Would disabling undo at the beginning of the 'group' and enabling
at the end of the 'group' do it?
