IIUC you want to skip anything but a left paren before starting the
scan.  This means you might skip the start of a comment or string and
end up before the first left paren within that comment or string.

The only right way to do that is to parse the syntax until point first
and handle the case where you are in a comment or string appropriately.
That approach has been suggested a number of times but so far no one has
implemented it.
