| /bin/sh uses /dev/tty for job control which is enabled automatically
| when running as interactive shell. But there is a -m option where
| you can enable/disable it, i.e. 'sh +m' runs a shell with job control
| disabled and descriptor 12 not open.
And that's correct, rather than what I thought when I replied to the
original message earlier.
| Maybe kre@ knows if a shell should allow redirection to its
| own internal file descriptors.
It shouldn't. Fixing that one is trivial. Fixing the fd 13 one is
trickier (but will happen).
| (Our) ksh only supports the single digit descriptors 0..9 for redirection
All ksh versions, I believe.
