Thatbeing said, I can change it to be consistent in the other direction.
 

AFAICT, handle_help_version_opts() does this correctly: It takes an 
argument fixed_progname that is used for --version output, while for the 
--help output it uses argv.  And most callers provide a fixed string for 
fixed_progname, but I see that some don't.
