according to Programming Perl (p. 98)...
-w = file is writable by effective uid/gid
-s = file has nonzero size (returns size)
-w only tells if the file's permissions allow it to be written to, has
nothing to do with whether or not it already has data.
save the return value of -s and check that value to see if the file
has data or not
