Basically, what Eli said.  To remind you how flexible this is: The
file coding system including EOL convention would be determined as it
currently: a specific argument to write-file or the binding of
buffer-file-coding-system, in that order.  The last would be
determined as currently: user's explicit setting, various settings
based on alists, and finally heuristic autodetection based on file
contents and platform convention for new/empty files.

We'd need an additional control variable: whether to automatically
convert variant NLFs to the EOL convention for writing.  Or perhaps
this should be done on reading.  And a command to do it at the user's
convenience.
