Ok...I think I see the confusion.  I thought that having a package in my
Imports is supposed to automatically suppress startup messages so that
library( my_package ) only shows info for packages that are attached, not
those that are loaded because they are imported.  I didn't realize that
some folks are implementing startup messages via onLoad.  The behavior
makes sense.  Thanks!
