Dear Maintainer,

when "double tabbing" on a newly opened shell, an error is printed on
the console (instead of the list of files)

claudio at Chuck:/etc/bash_completion.d$ bash: words: bad array subscript

This bug was reported also on Launchpad[1] for Ubuntu, and from there I
retrieved the fix, which is changing line 710 of
/usr/share/bash-completion/bash_completion
from

[[ $cword -eq 0 ]] && return 1

to 

[[ $cword -le 0 ]] && return 1

I've attached my patch.

Thanks,

Claudio
