Adam,

here is the answer i just received.

--- snip ----

The comparrison of '2' is to make sure you're not comparing it to a
string that just begins with a star.  E.g., you don't want it to match
"*foo".  So the '2' will make sure it only matches the "1-character"
string, "*" (which actually uses 2 bytes, the '*' and a NUL).

--- snap ----

Stefan
