Match special globals in Ruby better
* lisp/progmodes/ruby-mode.el (ruby-expression-expansion-re):
Match special global variables without curlies, too.
(ruby-font-lock-keywords): Simplify the matcher for special global
variables. Don't require a non-word character after the variable.
Fixes: debbugs:17057
