Well, then there's the case with the non-existing file and the other
case with an empty file.  What about this:

f=/tmp/ff && >>$f && [ "$(tail -c1 $f)" ] && echo >>$f || :;stat $f

>>$f		# like `touch', but no fork (makes sure the file
		# exists) so `tail' will not fail

tail -c1 $f	# on an empty file will return "" (as if there was a
		# a <newline> there

;stat $f	# is there just to show what's going on


Cheers,
