Subject: [PATCH] Propertize only perl prototype chars `][$%&*;+@\' as
punctuation
As a result, variables in signatures such as `sub add ($a, $b) are not
treated as punctuation.
* lisp/progmodes/perl-mode.el (perl-syntax-propertize-function):
Strictly match only prototype characters as punctuation. (Bug#26037)
