Define it as "difference between PROMPT1's width and the total width
of non-%w elements in this prompt". Then it has a defined meaning in
PROMPT1 too (which could be arbitrary if it appears only once, but
has to be zero in case it appears more than once).
Easter egg: expand it to backspaces if used in PROMPT2 among other
stuff that's already wider than PROMPT1. ;)
