     It's not built into CP/M at all.  It's just that most terminals
and hardcopy drvices of the time required both the CR and the LF to
get to the first position on the next line.

     Why don't you just scan for the CR?  If you find one, then look
at the next character.  If it's a LF, then throw it away.  If it's
not, you've got a weird file.

     You could always therminate the line at 80 characters or CR,
whichever comes first.
