Skip "bash: declare: -A: invalid option" error gracefully

Browse source 
The use of "declare -A flaghash" (associative array) was introduced
in PR #205, which works perfectly for Bash 4.x, but OS X insists on
shipping a very outdated Bash 3.2.x.

This patch hides the "bash: declare: -A: invalid option" error message
and allows the bash completion script to continue gracefully on
OS X, albeit without the benefit of the new feature in PR #205.

Fixes #240
