Interoperability problems have been observed with erroneous labelling
of paragraph text as Text/Plain, and with various forms of
"embarrassing line wrap." (See section 3.)
Attempts to deploy new media types, such as Text/Enriched [RICH] and
Text/HTML [HTML] have suffered from a lack of backwards compatibility
and an often hostile user reaction at the receiving end.
What is required is a format which is in all significant ways

This memo proposes a new parameter to be used with Text/Plain, and,
in the presence of this parameter, the use of trailing whitespace to
indicate flowed lines. This results in an encoding which appears as
normal Text/Plain in older implementations, since it is in fact
