Alex Richardson d146f83180 prepare-commit-msg: Avoid warning on macOS and shellcheck fixes

Replace `return 0` with `exit 0` to fix this. While editing this files
I've also fixed all the shellcheck warnings that were displayed by my IDE.

This directory tree contains tools used for the maintenance and
testing of FreeBSD.  There is no toplevel Makefile structure since

though there may be individual Makefiles in some of the subdirs.

Please read the README files in the subdirs for further information.
