Description:
        A simple expression can cause the error message
            unexpected EOF while looking for matching `)'
            syntax error: unexpected end of file
        the atachetd patch seems to work around ... maybe
        there is a better method in parse_comsub()

Repeat-By:
        bash -c 'echo $(echo aaa | egrep kernel.org\|rpmify)'
