the problem here seems to be that makewhatis isn't run by pkg when (new)
manpages are installed.

after discussing this with kevans and bapt, i think we can fix this by
using pkg-triggers(5) to run makewhatis after packages that contain
manpages are installed.  i'll probably combine with this splitting
mandoc into its own package.
