Thanks for a good report. I used this script:


   my $l= 'A' x 100;
   foreach my $i (0 .. 100000) {
       my $name = $i.$l;
       open(F, ">$name") or die "stupid program: $!";
       print F $name;

... and could easily repeat this problem locally. I then wrote a fix that
properly sends updated window size to the remote. I've now pushed my fix to
the git repo using hash 7194a9bd7ba45.

I'll appreciate if you test it and give us your comments!
