Be careful about shebangs, which shells are used, and what gets executed

Use
 - #!/hint/bash for bash that gets sourced (non-executable)
 - #!/hint/sh for sh(1) that gets sourced (non-executable)
 - #!/bin/sh for sh(1) that gets executed
 - #!/usr/bin/env bash for bash that gets executed

To this end, also
 - Clean up a couple of related comments
 - Fix a couple of bash-isms that I noticed in sh(1) files
 - Fix permissions on a couple of files that get sourced
