Changeset 12897126f239 made by Fabian Groffen in the MonetDB repo, refers to this bug.

For complete details, see http//devmonetdborg/hg/MonetDB?cmd=changeset;node=12897126f239

Changeset description:

ctl_handle_client: don't send double trailing newlines

Fix for bug #2984.  Due to sending too many newlines, the client code
interpreted the answer from the server as not being the exact string
"OK\n".  (Correct, there was another '\n').
