Doesn't look like something is wrong, or I'm missing something...

If there are chars left you write to the PP and take it out of the total

The second if is for translating \n to \r\n only if you've already
written everything (up to /n) to the PP

If count > 0 fails (that is, count == 0) you get out of the loop
