The docstring for sqlite-select says "By default, the return value 
is a list where the first element is a list of column names, and 
the rest of the elements are the matching data." But this isn't 
true, by default, the value of RETURN-TYPE in that function is 
nil, which does not prepend the list of column names. I don't 
think anything more is necessary then removing this line, because 
the rest of the docstring has sufficient explanation.

Patch included.
