I want a single function for Info to traverse all nodes linearly, i.e.
depth-first.  I'd like it to do Info-first-menu-item (`1'), and if
that fails, do Info-next (`n'), and if that fails, do Info-up (`u').
This seems to require using catch and throw, but from the description
in the Emacs Lisp Manual (1st ed.), similar to that in Steele's
Manual, I can't see how to apply them here.  Can someone help me?

I have my reasons for not using
	(if (search-forward "\n* menu:" nil t)
	    (code-for-finding-first-menu-item)
	  (code-for-finding-next-node) etc.)
but they wouldn't be of general interest quite yet.  Thanks.
