feedback: when the last line is empty, don't include it in the count

Now M-D will report 0 lines instead of 1 line for an empty buffer, and
will match the output of 'wc --lines' as long the file is a POSIX file.

This fixes https://savannah.gnu.org/bugs/?56054.

Bug existed since before version 2.1.10.
