Replace backtick command substitutions with $(), quote variable
expansions to prevent word splitting, replace useless cat pipes with
redirections, use grep -q instead of redirecting to /dev/null, and use
bash parameter expansion for case conversion.
Based on the work from PR #6366, rebased and adapted to current master.
Shebangs already merged separately via df64bf8fe are excluded.
