Yep, these are bugs.  However the patch doesn't fix these properly.
In  nextline, if  nvln == winh - 1 (or --ln as you put it), then 
you would still need to scroll one line and adjust nvln.
I'll look at this (after I get some sleep).
I was thinking about breaking up scrollwindow() into scroll a single
line and scroll a half screen.

And for Zoltan and others who want to use zed to edit their stuff
and want half window scrolls, chuck "local BAUD=2400" at the top
somewhere.  Other refresh styles will have to wait till after zsh 3.0
