Oh, you want a *workaround*.  Well, this is a basis of a workaround for one-line
text widgets.  You'll probably have to add sophistication to taste; I could
imagine using the userData to control a mode switch.

  XtAddCallback(text, XmNmodifyVerifyCallback, tcb, NULL);
.....
/*ARGSUSED*/
void tcb(w, d1, mvcb)
     Widget w;
     caddr_t d1;
     XmTextVerifyCallbackStruct *mvcb;
{
  if (mvcb->text->length == 1) {
    XtCallActionProc(w, "delete-next-character", mvcb->event, "", 0);
  }
}
