Can some one tell me this: 

I want to do an interactive command over a buffer with undo
information that will do some search-forward/replace-match commands
but without saving for undoing this information.

So, how do I do a command without saving undo info for it BUT,
preserving the previous undo information?

I need this because I have a command that will exchange 8-bit
accentuated characters to it's LaTeX representation and vice-versa and
I never want to undo this command (because of the vice-versa :-).

Please email me your answers because I dont read this newsgroup very
often.

Thanks in Advance
