BR 2593349: Move version message back to stdout

Checkin 4b9358928b114caaf34a69d6fdfd3b285b7a72cc changed the version
message from stdout to stderr, but:

a) doesn't motivate the change in the commit log;
b) bundles that with other changes;
c) is inconsistent with other programs;
d) was done by me and I can't remember any reason for it.

Hence conclude it was unintentional and therefore a bug.  Since this
commit was done after 2.05.01 no stable release has been affected.
