That's a chicken-and-egg argument, and I do not think it is a bug in
"-W" nor the funcname regular expression pattern we use.  We expect
a blank line there and the pattern reflects that expectation, so not
having an expected blank line is what causes this problem.

In any case, we should add a blank linke before the beginning of the
function, and of course that is obviously outside the scope of these
patches.
