From: Ted Pavlic <ted@xxxxxxxxxxxxx>
Adds a few simple comments above commands that take arguments. These
comments are meant to remind developers of potential problems that can
occur when the script is sourced on systems with "set -u." Any
function which "requires" arguments really ought to be called with
explicit arguments given.
Also adds a #!bash to the top of bash completions so that editing
software can always identify that the file is of sh type.
