What is this change about?  You do not have to align value columns.

Perhaps wrap it like this?

	if ((allow_unadvertised_object_request &
            (ALLOW_TIP_SHA1 | ALLOW_REACHABLE_SHA1))) {

Good, but push that to even more right?

Same issue as [2/3]

		...
	} else if (!strcmp("configVariable", var)) {
        	if (git_config_bool(var, value))
			value |= ALLOW_THIS;
		else
                	value &= ~ALLOW_THIS;

should be OK.
