upcoming Boot Environment menu. The Xen Kernel is dynamically appended after the last menuitem in the Boot Options submenu. If xen_kernel is not defined in loader.conf(5) the Xen Kernel menuitem displays "N/A" versus "On"/"off". While here, fix-up the pkg-message (make capitalization of "in" vs. "In" consistent; make use of trailing ":" consistent; move a comment out of the way of file contents, etc.).
