Look at the code: if there's an LF anywhere, the mac decoding fails
and reverts to unix style eol.

This is a current limitation of Emacs because it cannot distinguish
(inside an Emacs buffer) between an "LF character" and an
"eol character", so an LF char from a Mac-eol file cannot be decoded
to an LF (since it would be encoded back as a CR).  We could of course
decode them to something completely different (like CR which will
currently never be output by the decoding of a Mac-eol file), but then
people would find it rather surprising.
