bash: words: bad array subscript

[Barry Warsaw]

cd to your $HOME and without entering anything at the prompt, hit TAB. I get the error in the Subject.

The bug seems obvious: in /usr/share/bash-completion/bash_completion, line 710 you have:

    [[ $cword -eq 0 ]] && return 1

but `set -x` in a bash and doing the above shows $cword to be -1, thus the following line (711):

    prev=${words[cword-1]}

fails with the error.

The fix is easy. s/-eq/-le/ on 710.
