Modified Files:
	src/bin/dd: dd.c

Log Message:
Avoid corrupting the dd(1) IO streams.  This would happen by accidentally
outputting to the files being manipulated by opening a file in the standard IO
descriptor space.  In particular, an output file unlucky enough to be sitting
on descriptor 2 (stderr) is certain to be corrupted.

Addresses PR bin/8521, and passes the recently committed regression test
"bin/dd".
