The following was discovered by one of the users around here:

   Script started on Fri Jul 14 13:23:21 1989
   % bash			<== invoke bash here
   watmath[1]$ function CAT	<== define function CAT
   bash>{
   bash>/bin/cat $@
   bash>}
   watmath[2]$ CAT hi
   Hi!				<== this one is fine
   watmath[3]$ CAT hi >log	<== did an "ls" and "exit" here, not echoed
   % cat log			<== back to csh, look at the log file
   Hi!
   watmath[4]$ ls		<== "ls" and "exit" shows up in the log file!
   hi
   log
   typescript
   watmath[5]$ exit
   % exit

Once the output of a function is redirected, it stays redirected after
the function is completed.  This happens on all architectures we have.
It was discovered in version 1.01 and still exist in 1.02.

Thanks.
