bug#20566: perl-mode: maybe have the parentheses of s{a}{b} also blink

[積丹尼 Dan Jacobson]

I think I am saying that when one types in
if(1),
even here in a non-perl mode as I type this email message,
emacs makes the ( and ) very bright, indeed as long as I don't move the
cursor more.

So I'm saying that something just the same should be done
on s/a/b/ s{a}{b}
where all three /'s or all four brackets light up.

Well not only briefly, but it should stay lit, until the cursor moves
away, All four of {}{} too.

Same for [][], !!!, etc.
