This is a temporary transient-mark-mode (`only' mode) which is set by
the mouse.  This was recently changed to make the temporary mark less
fragile, so that it persists for some commands instead of deactivating
after the next command.  As a result, there are some commands that now
need to turn off the temporary tmm explicitly.
