Re: yank-handler

[Richard Stallman]

    If I kill a piece of a hunk and then yank it in some other buffer,
    the "[+-! ]" prefix added to each and every line should be removed
    (unless I'm yanking back into a diff-mode buffer or unless there's
    something like a "@@ -463,4 +463,36 @@" marker, obviously).

I have a bad feeling about this--it is the sort of thing
that makes the editor overall less controllable.  I would
prefer some sort of feature to copy part of a diff buffer
into the kill ring without these prefixes.
