Subject: [PATCH] Change the operator of the contacts picked in the log
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A multi-operator station logs a whole shift under whoever was at the
radio, so a shift logged under the wrong callsign had to be put right a
contact at a time. "Change Operator…" in the log's right-click menu asks
for one callsign and writes it against every contact picked in the grid.

The dialog offers the operators the program already knows in a drop-down
and takes any other callsign typed.
