None on output.
On input, "\n" disables universal newline mode altogether ("\r"
doesn't end a line), while "" enables universal newlines for
determining the line ending, but disables the *translation* part,
meaning you will get lines ending in "\r", "\r\n", or "\n" depending
on what's in the input. The default UN mode with translation is easier
for most apps (since it guarantees that lines end in \n like most apps
expect), but the UN mode without translation is handy if you want to
copy the file faithfully (apart from specific edits).
