Who/what is reading this /etc/bash_completion file? Is bash itself
automatically loading this file? I'm asking because on my distro, I
have /etc/bash_completion.d/ and no /etc/bash_completion.

It seems like my bashrc here is automatically
including /usr/share/bash-completion/bash_completion, and otherwise
falls back to /etc/bash_completion:

  if [ -f /usr/share/bash-completion/bash_completion ]; then
    . /usr/share/bash-completion/bash_completion
  elif [ -f /etc/bash_completion ]; then
    . /etc/bash_completion
  fi

Basically, my concerns are:

 - You are using ">" for the redirection. Are we going to be the only
   package writing to this file?

 - Do we support having other packages contribute additional bash
   completion logic?

Thanks!

Thomas
