Yes, that would be easiest, one just has to remove the static
keyword in the .c file and add the function prototype to the .h file.

Alternativly one could change the cmdline_parser_init function so that
it just calls init_help() if called with a NULL pointer. Currently,
such a usage would lead to a segfault.

OK, so I won't argue for this alternative any more :) But out of
curiosity, what were the problems in inplementing it this way?
