Re: require-hard-newlines to use newline

[Richard Stallman <rms@gnu.org>]

    I haven't thought really hard about it, but superficially, it would seem
    like a pretty common occurrence that the transformation should be different
    depending on the context (things like "was the beginning of the string at
    BOL?", or maybe for message-mode "is this taken from the header or the body
    of the email", ...).

It's often a mistake to aim for generality that goes beyond the uses
we have envisioned, because any easy job can be made hard if you do
that.  Anyway, it is easy enough to have a convention to put point at
the start of where the text came from, before running the hook
functions.
