[racket] No shortcuts on linux REPL

Were this a high priority, there are other line-editing libraries now 
(nobody likes the "readline" license).  Or we could make our own (it's 
not hard; just time-consuming to do for all the platforms).

But don't know that it's high priority.  I'm sure a few people 
(including me) occasionally wish the command-line REPL had "readline" by 
default, but I just made a shell script and moved on.  Most of the time 
I need a REPL, I use DrRacket or Quack, anyway, and I think most people 
do that.

#!/bin/sh
if [ $# = 0 ] ; then
     exec racket -Uilq readline
else
     exec racket -Ueq "$*"
fi
