There is a LF on CR option. I have one Model 15 with it, and one
without it. I don't know how it works.  Probably
some mod to the LF code bar. The 1941 manual doesn't mention
that feature, so it may be a later addition, like motor start/stop.
The machine with that feature also has auto CRLF at end of line, around
character 74, so you never pile up at the end of line or overtype a
previous line.

One of the options to my "baudotrss" program is whether this feature
is installed. Then it can compensate. That program also has word wrap.

My software approach to unshift-on-space is that the program has
three typing unit states - FIGS, LTRS, and "unknown". In "unknown"
state, the next character to go out for which the LTRS and FIGS shift
matters is preceded by LTRS or FIGS. When a space is received in
FIGS mode, the state goes to "unknown", to force sending a LTRS
or FIGS before the next character where it matters.
