Trac Ticket #453 - db2index with -tattrname:type,type fails
    
    https://fedorahosted.org/389/ticket/453
    
    Fix Description:
    1) db2index and db2index.pl did not handle options with no space
    between the option type and the value.  This patch properly parses
    them.
    2) db2index_add_indexed_attr now converts the comma delimited list
    of index types into multiple values for the nsIndexType and
    nsMatchingRule.
