On Windows too?  I didn't know that.

Are you arguing that typing 'o' (rmail-output) will write
DOS EOL file when EOL type of buffer-file-coding-system of
rmail buffer is undecided and the system_eol_type is DOS?
Then, isn't it a bug of rmail-output?

The reason I decided to leave EOL type undecided is for the
case of M-x write-region on rmail buffer.  In that case, I
think, following system_eol_type is the right thing.
