Yes, except that I'm not sure about the name; maybe "plain"?

This isn't just an issue for batch jobs; my usual "terminal" is
XEmacs' shell-mode, which doesn't process ^H (or ^M or ^G for that
matter).

[For programs which use ^M, you can at least use "stty ocrnl".]

Maybe a better solution is to allow the specification of an arbitrary
string which is used to "rewind" percent output.
