Sure, but in newer versions, they might update their code to follow
the standards after all... wouldn't they?

True; and I haven't tested the code either, to be honest. I found the
basic implementation on a forum somewhere and adapted it to the
threadstarter's need.
I might try and see if I could submit a documentation bug on this. I think
it's a useful feature and you're right to claim that since it's not
documented, one should not rely on it.

Hey, totally agree here, BUT, the threadstarter doesn't mention it being
put in a database. Actually, he just requests it to be written on a new
line in the output. I just provided him a way of doing this.
I always store the input directly in the database (quoted, then, of
course) and replace \r\n with <BR> when needed (display on screen). I've
had no problems by strictly using \r\n yet. But as I have an open source
project, I assume someone will (be telling me||submit a bug) if they have
problems. In that case, I will implement a non-W3C compliant hack ;)
