Reading more than one expression on the same line

I sent this patch in April, but didn't get any response. So here it
is again...
When readline is *not* activated, this is what you see if you type two
expressions on the same line and press enter:
guile> 'a 'b
a
guile> b
guile>
Whereas I think it would be more natural, and less confusing, to see:
guile> 'a 'b
a
b
guile>
If the consensus agrees with me, the fix is to modify repl-reader in
boot-9.scm so that it only displays its prompt when there is no input
already available, as in the following patch.
Regards,
Neil

input already available.
