>Description:
/bin/sh doesn't handle noclobber option and 2>/dev/null redirection
at the same time.  Script fails just silently and aborts further
execution. This can be overridden by using 2>|/dev/null instead
(n<>| overrides -C).

Still what concerns me is the difference in behavior of /bin/sh
and /bin/ksh. With ksh it works just fine. Is this intended behavior
of /bin/sh or a bug?

>How-To-Repeat:
#!/bin/sh
#
# Empty file with "testfile" name should be created,
# if it doesn't exist yet. 
#

set -C
2>/dev/null > testfile && echo "yes, it works!"

 I believe this is fixed in NetBSD current.   Not in 7.0 though.
 I'm not sure if pullups of the fix to -7 and -6 are appropriate
 or not.
