Re: Undo discard prompt (was: [T. V. Raman] read-only modes should be using buffer-disable-undo?)

These changes are good.

    I propose one more small change to lispref/text.texi:  Replace the three
    defvars for the undo-* variables with defopts, because they are all
    three customizable and it actually makes a lot of sense to customize
    them.

Yes, thanks.
