Title:
  python tab-completion error: bash: COMP_WORDS: bad array subscript

Status in bash-completion package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: bash-completion

  When I'm specifying the full path to a Python interpreter (which is
  very common for Python developers who use zc.buildout or virtualenv),
  attempting tab-completion of the first argument results in errors.

  To reproduce:
    1. touch python script.py
    2. chmod +x python
    3. type ./python scri<tab>

  Expected output:
    ./python script.py

  Actual output:
    ./python scribash: COMP_WORDS: bad array subscript
    pt.py

  The bug is in /etc/bash_completion.d/python, line 26.  If I replace

          [[ ${COMP_WORDS[COMP_CWORD-2]} != -@(Q|W) ]] && _filedir

  with

          [[ $COMP_CWORD -ge 2 ]] && [[ ${COMP_WORDS[COMP_CWORD-2]} !=
  -@(Q|W) ]] && _filedir

  then completion works without emitting spurious errors.
