I like adding /usr/local/bin to defaultpath, something /bin/sh
doesn't do, because rc doesn't source .rcrc unless it is a login shell
and more localized defaults makes rsh work better.

But it works just barely well enough for SunOS, which has no /dev/fd

If anyone ever ports it to Plan 9, it might be handy.
(I get an urge to do this every time I hit a feature that your
