Even in the self-test suite, the bug appears, run:

python /usr/lib/python2.4/curses/

then type so that the line wraps, eg 123456789123456789 to fill two 
lines, and then ctrl-g to return -- the result has had the end 
characters of each line removed, so the return value is 

As a quick hack on my local install I changed line 56 from:

last = min(self.maxx, last+1)


last = min(self.maxx, last)+1

and it seems to work, but I have no idea if this is the right way to 
fix it (ie, this might have side effects, or this off-by-one might 
happen in several places and need a global fix, not just one local one)

This doesn't happen to me with 2.6 compiled from HEAD, or with 2.5.2
shipped with Ubuntu Hardy.

In both cases the output is:

Contents of text box: '123456789\n123456789\n'
