Use proper names (i.e. zfs-allow and zpool-add) in NAME subsections of zfs/zpool subcommands instead of current "pretty-printed" ones as makewhatis utilities (or some implementations of it, namely the one from mandoc suite used in FreeBSD) look not only at the document title but also in NAME subsection, adding zfs(8)/zpool(8) to search results which is not correct. (Common sense and other utilities splitting subcommands in multiple man pages, e.g. git, do the same.)
