I think all that we really care about is that the load+save trip is safe
and that the content of the Emacs buffer looks "as right as possible".

In Stephen's case, clearly CRCRLF should be consider as CR+eol and there
does not need to be any heuristic for that.  It's perfectly safe and can
only be the right choice for the internal representation.

I.e. if all LF are preceded by a CR we should use "dos-eol" whether or
not those CRs are sometimes preceded by other CRs.
