Well, it should be updated. If the test fails, this maybe means that
the previous command returned "yes" plus some other non-printable
characters that you don't see, but makes the test fail. I used to have
such problem when running octave within a terminal that couldn't
handle all control sequences.

You can safely do that. This is not used for the moment.

You can safely ignore that. These are just warnings.

Yes. JHandles package is not autoloaded. Either use the -autoload
switch when installing it, or simply type 'pkg load jhandles'.
