>Description:
	when running a background job that contains >&- (or <&-) or
	>& N (or <& etc) (where N > 9) the "jobs" command fails to
	display the redirection correctly.

>How-To-Repeat:
	$ exec 12>&1
	$ sleep 10 2>&- >&12 &
	$ jobs
	[1] + Running                 sleep 10 2>&/ >&<

	Notice that '/' == '0'-1  and '<' == '0'+12 and you get
	a hint as to the cause of the problem...

>Fix:
	Coming soon to a shell near you.
