I don't agree with that. Since AFAIK, <LF><CR> is a combination not used by any OS, 
it shouldn't be processed as a single EOL.

For me, <X><LF><CR><LF><CR><X> should be seen as <X><Unix EOL><Dos EOL><Mac EOL><X>
It is a bit convoluted, but it is logical...

Experience shows that it can happens, althought it is a quite extreme example.

You can do it with SciTE, for example, changing the EOL mode twice.

I have seen Dos files edited with vi on Unix systems, with mixed EOLs. Compiler was 
smart enought to cope with these files (after all, in C, <CR> and <LF> are still 
whitespace-like), but some editors choked on it.
