cond without an else clause produces no values

I am using Vicare Scheme 0.4d1.1 on Debian GNU/Linux 8.7 amd64.

The cond syntax is not behaving properly when there is no else clause. The following expressions should all return 1:

vicare> (cond (#t 1))
vicare> (cond (1))
vicare> (cond (else 1))
$1 = 1

This is on purpose. It is explained in the devlog. I have not yet properly documented these changes. Sorry.
