Not sure I understand.  Is the idea that use of startup_info->help
is a marker for "I've checked this code path"?

If that were the only reason, I don't think I'd like the idea.

As it is, I'm a bit conflicted: what if we decide to short-circuit
"git foo --help-all" in the future just like we short-circuit
"git foo -h" now?  Would that require a separate flag?

In other words, I'm not sure startup_info->help is a good abstraction.
Maybe (modulo names) it would be better to do

struct startup_info {
	...
	const char *short_circuit;	/* "-h", "--help-all", "--no-index", or NULL */
};

and use

	if (!strcmp(startup_info->short_circuit, "-h"))

to allow relaxing the argc == 2 check later?
