Anyone ever noticed this?  We're running Ultrix-32 V3.1B 
on a VAX.  The use of double quotes and back quotes seems to 
cause octal 377's to be interspersed with regular output.  
I seem to recall seeing this mentioned somewhere (perhaps in this 
newsgroup).  Anyone know why csh does this?  Neither bash nor 
sh seems to do this, nor does any other UNIX machine I have tried.
