Should I commit 29049 ?

[Bart Schaefer <schaefer@xxxxxxxxxxxxxxxx>]

I never did so because I'm not sure it's really doing the right thing.
IIRC (which I may not) the problem here is that we've exited and re-
entered the line editor, which means the call stack isn't useful for
saving/restoring the state, so this is attempting to cobble it up from
globals.  But maybe there's a better way.  In particular I think some
testing while I was preparing to commit revealed that this sometimes
backs out too much, but I didn't get a good set of steps to reproduce.

} I think this is almost right -- origll should probably be set to
} minfo.pos rather than minfo.end, and to be thorough there probably
} ought to be an "else" for the case where minfo.cur is NULL (but I
} suspect it's not possible for that to happen).
