The multiple-dives-edited message was shown even if the value was not changed. Notably, when tab-flipping through the dive fields. Therefore, changed the execute_edit() function to return zero when no command was executed. For this, return a boolean from the execute() function indicating whether the command was really executed or trashed. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
