I remember being confused when I read in some Tandy docs that "character
13 is newline". It might have been the same document that said that
"RS232" meant "Radio Shack 232".

My DTC300's (Hitype I daisy wheel) permitted extensive use of 0Ah as
linefeed WITHOUT carriage return in plotting mode, and could use CR
without LF for BOLD, overstrike, and underline.
My first DTC300 didn't have a working "Auto LF" switch, but when Jim
Bertera fixed that for me, I finally got my TRS80 to print. Prior to
that, it was in "paper saving mode", and printed each page of text on a
single line. (Electric Pencil and Scripsit)
I'm far from expert in it, but for 30+ years, I've been struggling with
implementation dependent interpretations of newline, and was suggesting
that that might be at the root of the missing newlines in some mail
quotes. Consider the possibility of a crude filter to convert CRLF to CR
by deleting all LFs. Now feed THAT some text that uses LF for newline.
That's why THAT filter should only delete the LFs that follow CRs.
