/editbox -r is great, but it would even better to have /echo be able to interpret newlines as well.
/echo -pN where N is an or'd value with crlf=1,lf=2,cr=4 with a default to N = 7 for all of them would allow us to have a better control over when to split on newline, you might want to split at crlf only and not cr etc. If possible I would like to see /editbox -r be extended like that as well.
echo -p7 interprets all of them
echo -p1 interprets crlf only
echo -p2 interprets lf alone only
echo -p3 interprets crlf & lf alone only
echo -p4 interprets cr alone only
echo -p5 cr alone & crlf etc
