As I said, if (according to your example) you ask for foo TXT, you do 
not follow the wild card because foo is a name in the zone.  BIND 
9.3.3. does this.  The algorithm followed is in RFC 1034, 4.3.2, in 
particular, step 3 a.

Here's much more detail on my test.  Note that the * has an MX, and 
beached-whale does explicitly exist without an MX.  Hence, asking for 
beached-whale's MX results in no data:
