As I already said, making internal call to libified part (perhaps in trailer.c) would make this part of conversation a moot point, but in general you can find

	argv_push(&child.args, "cmd2");
	if (... some condition that involves variables parsed out ...
            ... by parse_options() of implementation of cmd1 ...)
		argv_push(&child.args, "--option-for-cmd2");
	...
        run_command(&child);

in implementation of cmd1 that calls out to cmd2.
