Third in a series of patches that make bash completions more robust to
different interactive shell configurations and editors.

[PATCH 3/3] Adds a #!bash to the top of bash completions so that editors 
can recognize
  it as a bash script. Also adds a few simple comments above commands that
  take arguments. The comments are meant to remind editors of potential
  problems that can occur when the script is sourced on systems with "set
  -u."
