Octave defines progam_invocation_name to be the full invocation name
as invoked by the user (presumably gotten from argv[0], e.g.,
"/usr/bin/foo"); it defines program_name to be its basename (e.g.,
"foo").  See <http://octave.sourceforge.net/index/f/program_name.html>.

This seems like a reasonable convention, and would help justify having
two different variables.
