Redirect completion to sub-process

[frankcarey]

It would be awesome if bash-completion could be redirected down into the subprocess.

Example command:

commands:
  complete:
    cmd: git

When I type ahoy complete <TAB>, I get nothing (process hangs because the current setup is actually calling the 'git' command instead of forwarding the to it.

It looks like we might be able to simulate keypresses using echo -e "\t" | git See : http://stackoverflow.com/questions/6264596/simulating-enter-keypress-in-bash-script
