It's a problem with the comment, this is only for lone bytes. I can

Well it is one way to fix that bug I mentioned. The bug is real. And
stream_Peek() blocks and internally attempts those next reads until the
requested amount of data was read, and the code always requests a bigger
(and even) data length, so the only way a lone byte would be returned is
that EOF was indeed reached.
If not, then we'd already have a more serious problem with line
splitting being completely broken for the same reason.
