Several ports had rc.d scripts with hardcoded command_interpreter string
as /usr/bin/perl. This symlink is not guaranteed to be in place, and it
isn't even an option for perl 5.20. For affected ports, the interpreter
was changed to localbase.
In one case, the interpreter was correct, but it wasn't surround by
quotes. Since the rc.d script would break if a space was contained in
${PREFIX}, quotes were added in that case.
literal name_enable wherever possible, and ${name}_enable
when it's not, to prepare for the demise of set_rcvar().
In cases where I had to hand-edit unusual instances also
modify formatting slightly to be more uniform (and in
some cases, correct). This includes adding some $FreeBSD$
tags, and most importantly moving rcvar= to right after
name= so it's clear that one is derived from the other.
