Good question... sometimes there are good reasons to show the layer
block even if there are no classes.  You can think of WMS or raster
imagery layers for instance.  However there should be a mechanism to
more easily disable the leg_layer_html block when no classes are present
(likely using the opt_flag parameter).  I've filed this in bugzilla and
will try to do something about this later this week when I get back to
MapServer bugs:
