"-symbols NAME" is a typo, should be "-symbol NAME".


Any preference on keeping or removing the "(s)" in the description, e.g.

  Only output documentation for the given function(s) or DOC: section title(s).

versus:

  Only output documentation for the given symbol or DOC: section title.

I think it makes sense to drop the "(s)" as each option can only specify a
single symbole, i.e. the "(s)" behavior is covered by "May be specified
multiple times."
