Undo manipulation

[Bill Wohler <wohler@newt.com>]

I don't want to add some manipulation to buffer-undo-list. For
example, let's say I have:

  1. blah
  2. blah
  xyz
  3. blah

and I want an undo to hit #3, then #2 and then #1, leaving xyz alone.
Are there normal ways to do this? Like inserting markers in
buffer-undo-list to later remove desired elements.

It just occurred to me that I could save buffer-undo-list into a
temporory variable, do my thing, and then restore the variable.

Thoughts?
