t4027,4041: Use test -s to test for an empty file

Browse Source 
The tests used a mixture of 'echo -n' (which is non-portable) and either
test_cmp or diff to check if a file is empty.  The much easier and portable
method to check for an empty file is '! test -s'

While we're in t4027, there was an excess test_done.  Remove it.
