That is only the half part of the story:
A non-binary line SHOULD BE terminated by an LF, which if present
MUST be included in the total length. Receivers MUST treat pkt-lines
with non-binary data the same whether or not they contain the trailing
LF (stripping the LF if present, and not complaining when it is
missing).
How do we treat pathnames ?
They can have each byte value except '\0'.
What should a receiver do, which reads a string like "ABC\n\n" ?
Is it "ABC\n" or "ABC\n\n" ?
I would really consider to treat pathnames as binary, and not add a trailing '\n',
are there other opinions ?
