These were why i was coming here.
It is one thing to write a 5322/I-M-F parser who documents RFC
5234, B.1. Core Rules "WSP", but simply skips over anything
whitespace related, effectively, but the other to digest a lone LF
or CR in the data stream.
So the answer is this they are not.

Thank you very much for this confirmation, i was very unsure.
