Since it is downloaded over HTTP (unauthenticated), it could be
anything. 746 bytes is really small.

Maybe we can change the Sourceforge URLs used by Guix to avoid
redirecting to an HTTP URL.

From here, it works okay:

------
$ guix download http://downloads.sourceforge.net/project/cunit/CUnit/2.1-3/CUnit-2.1-3.tar.bz2

Starting download of /tmp/guix-file.29mS0e
From http://downloads.sourceforge.net/project/cunit/CUnit/2.1-3/CUnit-2.1-3.tar.bz2...
following redirection to `https://managedway.dl.sourceforge.net/project/cunit/CUnit/2.1-3/CUnit-2.1-3.tar.bz2'...
 …-3.tar.bz2  502KiB                                                                                                                                  2.4MiB/s 00:00 [##################] 100.0%

------

If you want, you could save the downloaded file for inspection:

$ guix download -o cunit.tar.bz2 http://downloads.sourceforge.net/project/cunit/CUnit/2.1-3/CUnit-2.1-3.tar.bz2
