I remember that there has been discussion some years ago

that if there is a space immediately before a line break,

What happended with these ideas? Did they ever become a
standard, or a de-facto-standard?
I believe that you're referring to a content markup language known
as "format=flowed", which is described in RFC 3676. There was a
long discussion on ietf-822 ca. February-August 2003, including
an attempt to define a syntax for that content markup language
(though I don't think there was ever a conclusion to that effort).
The format seems to be used and understood by only a few MUAs; it
causes quoted material, particularly with copy & paste, to be
formatted in extremely long lines in other MUAs.
Also, as it employs (rather complicated, judging by the syntax
discussions) content markup, it seems inconsistent with the
intent of the text/plain media type (RFC 2046 section 3):
The five discrete top-level media types are:
(1) text -- textual information. The subtype "plain" in
particular indicates plain text containing no
formatting commands or directives of any sort. Plain
text is intended to be displayed "as-is".
and section 4.1:
Plain text does not provide for or allow
formatting commands, font attribute specifications, processing
instructions, interpretation directives, or content markup.
