Double quotes being added to return answers

Hi Brad,

Unbound internally deals with TXT records in wireformat, double quotes
are not added or removed.  I think the quotes you see are because of
multiple string sections in the TXT wireformat (each gets printed with
quotes around them).

The python .append function takes a text string and converts it to
wireformat.  I think the lack of quotes in there makes the parser use
whitespace to separate strings?  Try the append with quotes around
your content:  "%s %d IN TXT \"%s\""  (if that is valid python to
escape with \").

Best regards, Wouter
