It may seem similar, but I don't think it'd work out very well. The menu 
screen, in many cases, alters the bindings such that easy-to-use keys perform 
common menu operations. I suspect that doing this to the help screen owuld make 
navigating it noticeably more difficult. One such override is that the menu 
screen uses the routing keys for choosing a setting. Using the routing keys for 
regular cursor routing is, however, IMO useful within the help screen in order 
to easily mark a reading location to return to later.

Since I believe it's a generally useful change, I did go ahead and alter the 
"go up to previous paragraph" function to go to the first (rather than to the 
last) line of the previous paragraph. This does indeed make the two functions 
(go up/down to first line of paragraph) work very well for skipping through the 
headers within the help screen. Could y'all please give it a try?

Also, if anyone thinks that this change is a bad idea, just let me know. It can 
easily be removed. Do try it first, though. I find myself wishing that it had 
worked this way from the outset.
