Looks like a mismatch between the code and the spec.

The spec says of n*wildlsearch:

     1. The string may begin with an asterisk to mean "ends with".
...
     2. The string may begin with a circumflex to indicate a regular
        expression.
...
     3. Although I cannot see it being of much use, the general matching
        function that is used to implement (n)wildlsearch means that the string
        may begin with a lookup name terminated by a semicolon, and followed by
        lookup data.


In fact (if I'm reading the code correctly), n*wildlsearch turns each key in the
file into a one-item string list, and then applies list matching on that. It
appears that "10.3. File names in lists" applies here, but (to me) it's
unclear what other parts of section 10 apply. Section 10 is entitled
"Domain, host, address, and local part lists" - note NOT string lists.

Or I could be reading the code completely incorrectly :-)
