I propose to add the following paragraph:
Authors intending to use the LWSP (linear white space) construct
should note that it allows apparently empty lines consisting only
of trailing white space, semantically different from really empty
lines. Some text editors and other tools are known to remove any
trailing white space silently, and therefore the use of LWSP in
syntax is not recommended.
