Re: Top line clipping destroys Gnus

I really should have a look at your patch...Sigh.. What does this do
for the line_start_cache? My current opinion about the some of the
assert(cur_elt>=0) crashes that particular assert makes unwarranted
assumptions and that your change will increase the number of cases
of this. That isn't a problem with your patch but rather with the
line_start_cache, it contains loads of undocumented assumptions.
However, Hrvoje forgot to ask the obvious question:
What does (window-start) give in the case of a clipped first line?
