How do I find files that do not end with a newline/linefeed?

Question

How can I list normal text (.txt) filenames, that don\'t end with a newline?

e.g.: list (output) this filename:

$ cat a.txt
asdfasdlsad4rand

This is kludgy; someone surely can do better:

for f in `find . -name '*.txt' -type f`; do
    if test `tail -c 1 "$f" | od -c | head -n 1 | tail -c 3` != \\n; then
        echo $f;
    fi
done

N.B. this answers the question in the title, which is different from the question in the body (which is looking for files that end with \n\n I think).
