Convert the patch in the "context diff" format which no longer correctly
applies by the modern FreeBSD patch(1). Patch was applied on the FreeBSD
8.4 and then regenerated with ``make makepatch''. While here, replace
hardcoded ``/usr/local'' with ${LOCALBASE} as appropriate, merge in the
change made with sed(1), and typofix + shorten the COMMENT text.
