Ugh. I didn't even know we had such a thing. Those look like the only
ones that should be a problem, though. I'm glad to have factored out the
"want" code, now. At least it will all be in one spot.

Should this perhaps be:

  if (*placeholder == '+' || *placeholder == '-')
    placeholder++;

  switch (*placeholder) {
    case 'N': w->notes = 1; break;
  }

so that it will extend naturally if other placeholder lookups are needed
(since those ones also could have + or - markers).

Also, I just noticed that your case is missing a 'break'. Not a bug yet,
but it will be if somebody adds a new case. This is almost certainly my
fault from the original version I posted. :)
