        src/bin/sh: eval.c eval.h main.c redir.c

Log Message:
Finish the fd reassignment fixes from 1.43 and 1.45 ... if we are moving
a fd to an unspecified high fd number, we certainly do not want to hand
that high fd off to other processes after an exec, so always set close-on-exec
on the result (even if lack of fd's means no fd alteration happens.)
This will (eventually) allow some other code that sets close-on-exec to
be removed, but for now, doing it twice won't hurt.   Also, in a N>&M
type redirection, do not set close-on-exec if we don't want it.
