Render hr() faster

Render hr() faster by eliminating the requirement to fork and execute
any external utilities after having established the intended length of
the rule. Also, use printf -v and string-replacing parameter expansion
where the shell is found to be bash. Doing so helps considerably because
bash is very slow at looping.
