6433 - render newlines correctly

There were three confounding issues to get past before this seemed to be
working right:
  - row/col count from 1 rather than 0
  - I was thinking in decimal rather than hex
  - print-byte buffers to stdout, but print-string does not. I didn't think
    this mattered, but it does matter to flush the current line before
    moving cursor again.

Only one of these issues was a bug in the code. The first two were bugs
in my mental model that necessitated no changes to code to be corrected.
