nano: On Oldworld PowerPC, nano freezes machine when help is being displayed

This problem doesn't occur on my newworld powerpc, but it is 
reliably repeatable on my oldworld. I don't know why that
would be. I suspect it has something to do with some recent 
change in the ncurses library. I run the testing distribution, 
and often do brand-new installs to help test boot-floppies. This 
started happening a few weeks ago. I am also getting crashes in 
dselect which uses the same ncurses library. I also tried a new 
woody install on my newworld and verified it doesn't happen there.

I also verified that the same thing happens if I install on a 
different partition, even a different disk. It is definitely in 
the libc or more likely libncurses5 for woody, maybe there was 
some issue with the way they were compiled that made them incorrect 
for oldworld powerpcs.

Next, I'll try checking into ncurses - but no promises. At least 
this patch should do no harm to anyone else and it seems to fix 
the problem for nano. 

The crash occurs mainly when nano is trying to display help. I also 
had it crash once when pushing a character clear out to 
the end of a line, then selecting page-down.

The patch just uses wredrawln to claim that the 2 help lines are 
corrupt and asks for them to be completely redrawn rather than 
just refreshed.

Let me know if you would like me to test an updated curses or you 
have any other ideas.
