This makes HEAD a filehandle to the file.
push @head, <HEAD>;
would put the filehandle access into a list context, and would try to
append the entire file to @head.

This is a loop that counts lines that you want added, so you only want
one line added each time through the loop.
scalar <HEAD>
puts the filehandle access into a scalar context so that it will only
return one record each time. =o)
