`echo "^G\c"` behaves as expected when interpreted by the Bourne
shell, while `echo -n "^G"` behaves as expected when interpreted
by the csh.  "U**X 4.2/SYS5 on a Data General" (a.k.a. DG/UX) gives
you the best of both worlds, with both shells, each with the built-in
command "echo" behaving as expected.  To get Bourne shell behavior from
the csh, just use /bin/echo; to get csh behavior from the Bourne shell,
exec off a csh to handle the echo.

(By the way, the quote given in Knuth is "On a clear disk you can
seeK forever".  Makes a little more sense that way.)
