identifier to the closing ')' is the $0 argument".

The spec does not elaborate on where is the end of the identifier and the start

whitespace may be arbitrarily replaced with <br><br>. :)

The start of the argument might have been defined as the first non-whitespace
character or the first vertical space character, whichever comes first.
