>Release:        FreeBSD 2.0-BUILT-19950603 i386
>Environment:

	Intel 486DX4/100
	20M RAM
	S3 VLB video card
	X11R6-3.11
	SCSI disks only
	all of this information is totally irrelevant beceause
	the problem will manifest itself on any FreeBSD-2.?? platform

>Description:

	When vi executes a shell command it will print the error
	message "stty: TIOCGETD: Operation not supported". 
	FreeBSD-2.?? does this, no other version of vi have
	used does this including FreeBSD-1.1.5.

>How-To-Repeat:

	- open a vi session with a text file.
	- move the cursor to the beginning of a line of text.
	- enter the command !}cat followed by a CR
	- the correct response ids for cat to echo the input
	  data and there to be no apperant change to
	  the file.
	- The response of FreeBSD-2.?? vi is to insert a line with 
	  the message "stty: TIOCGETD: Operation not supported",
	  this is incorrect.

>Fix:
	
	I assume vi tries to perform a stty before executing an
	external program (in this case `cat'), the stty has invalid
	parameters. I suspect the fix is to simply remove the offending
	call to stty, but I haven't looked at the code.
