I have fixed the bug, and I will send the fix to Brian. Here's what I get
now:
usenet$ type rv
rv is a function
rv ()
{
[ $# = 0 ]&& {
local line=empty\?\?\?;
read line|| return;
echo Read: "$line" 2>&1 ;
rv;
echo "$line";
return;
};
local f=$1;
shift;
[ $# = 0 ]|| rv $*;
rv <$f ;
}
usenet$ rv ~/foo

It required changing a single line of code. Funny how this one hasn't hit
before; *all* instances of functions executing `return' have always had
this bug.
