Bug reference:      6327

Description:=20=20=20=20=20=20=20=20

Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D=3D

'goog:*'  matches  google.com
but
'e-goog:*' does not match e-google.com

Example SQL
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Try the queries below. Note ismatch column, which is t in the former, and f
in the latter case (IMHO should be t in both).

SELECT a query, b message, a@@b ismatch FROM (
   SELECT TO_TSQUERY('english', 'goog:*') a,
          TO_TSVECTOR('english', 'See google.com') b) as foo;

SELECT a query, b message, a@@b ismatch FROM (
   SELECT TO_TSQUERY('english', 'e-goog:*') a,=20
          TO_TSVECTOR('english', 'See e-google.com') b) as foo;
