rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable). these days, people use source. these id's do not provide

Redress PR 1547. Provide an option to pass high characters without
escaping, and turn it off by default. Checked by angelos@.

Don't bother calling nl() in init_display, just do the '\r' -> '\n' conversion
