review - breaking -ab into -a -b when needed and --foo=bar into

[BradleyA]

Look at this for further parsing

# --foo bar

        # Add current char to options
        options+=("-$c")

        # If option takes a required argument, and it's not the last char make
        # the rest of the string its argument
        if [[ $optstring = *"$c:"* && ${1:i+1} ]]; then
