One possibility is to just let them set a boolean flag that says they
want to use the platform-specific line ending for their platform. That
makes the call a lot clearer than
What you lose is the ability on a Mac to write \n line endings, and any
other mix and match. But we also lose the concern that someone will go
crazy and set the separator to "<br>". :-)
Do people see use cases where you really want to set a separator other
than what's on your platform? If so, we could use constants of MAC,
WINDOWS, or UNIX but keep away from letting someone specify a string
themselves. That would cover all reasonable use cases I'd think.
