I would prefer a new constant named lineEnd that is _Revolution_ 
specific.  This would allow the same stack to move across platforms 
without line end changes.  For backwards compatibility, it should 
be ASCII 10.  Maybe there can be a short name, but line and end are 
already taken.

With that, new constants asciiCR, asciiLF, and asciiCRLF are also 
defined.

With the above, use of return and CR can be discouraged.  And 
lineFeed and CRLF need not be used.


However, I've seen examples from old timers on the list that 
include return quite a bit.  I find that jarring and sometimes 
confusing.  Yet, others might find it quite natural.
