Transcript: Try to match the formatting of the original code.

A big diff, but these are just whitespace changes. This probably isn't 100%
correct yet, but at least there aren't any pages that look completely different

Correct 1972 SETBRK transcription.

The fifth character in the 1972 SETBRK argument list is difficult to read in
the scans. But if we assume that the list is unsigned from the 1969 version,
this should be a "-".
RATOM should obey the SETBRK list

RATOM is controlled by the function SETBRK and SETSEPR. So we should use the
characters specified by SETBRK here. (SETSEPR is just used to configure the
ordinary whitespace characters and thus can be ignored.)

This changes how words containing "-" are parsed.
