Summary: warnings from Net::FTP::I.pm

Initial Comment:
sub read {
...
  while(($l = length(${*$data})) < $size) {
   $n += ($b = sysread($data, ${*$data}, $blksize, $l));
   last unless $b;
  }
...

From time to time I get:
   # Use of uninitialized value in addition (+).; Line 29

I set $n to 0 before starting the loop. This didn't resolve the issue.
How come sysread() called in this context returns undef?
