loop brace code a bit obscure

[sf105]

This code

case '{':
  count = x; 
  loop = buf;
  while ((ch = *buf++) && ch != '}') {}
case '}':
  if (count) {
    count--;
    buf = loop;
  }
  break;

depends on the '{' case falling through to the '}' case at the end. I just blew a day porting to another process where I didn't notice this. How about

case '{':
  count = x; 
  loop = buf;
  while ((ch = *buf) && ch != '}') { buf++; }
  break;

Not quite as efficient but much safer?

Sorry about the day.
