The automatic detection is useful when the programmer doesn't care which
format is used, but wants to provide a consistency for the user.  This is
true for the 'error' program.

Regarding CRLF->LF translation for input streams.  Are you saying that when
a programmer reads from an input streams that, as a programmer, they should
only have to expect LF characters?  Is this too unix centric?  I haven't
done programming on windows for a very long time, what would a windows
programmer expect?

Yep, I'm no expert here.
