Fix prompt for join-pane.

The argument to join-pane is a pane specifier.  If no dot is used to
separate the window and pane parts, join-pane treats the argument as
a window and joins pane zero from that window.

Thus strictly speaking the pane part of the command prompt should be
shown as optional rather than the window part.
