True, but the problem is that the brackets don't correspond.  There are
two brackets on the left, options and "Pattern", and "S+" in the left
bracket is not related to the "only" options.  If we had used braces:

	\df{antw}[S+] [PATTERN]  list {only agg/normal/trigger/window} functions

that would make sense, but we don't have space nor are braces logically
correct for this usage.
