Properly format NAME subsection of zfs/zpool subcommands
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.)

.Dt ZFS-PROMOTE 8
.Os
.Sh NAME
.Nm zfs-promote
.Nd Promotes a clone file system to no longer be dependent on its origin snapshot.
.Sh SYNOPSIS
.Nm zfs
.Cm promote
.Ar clone-filesystem
.Sh DESCRIPTION
.Bl -tag -width ""
.It Xo
.Nm zfs
.Cm promote
.Ar clone-filesystem
.Xc
The
.Cm promote
command makes it possible to destroy the file system that the clone was created
from.
The clone parent-child dependency relationship is reversed, so that the origin
file system becomes a clone of the specified file system.
.Pp
The snapshot that was cloned, and any snapshots previous to this snapshot, are
now owned by the promoted clone.
The space they use moves from the origin file system to the promoted clone, so
enough space must be available to accommodate these snapshots.
No new space is consumed by this operation, but the space accounting is
adjusted.
The promoted clone must not have any conflicting snapshot names of its own.
The
.Xr zfs-rename 8
subcommand can be used to rename any conflicting snapshots.
