[Libguestfs] [libnbd PATCH 1/3] dump: Document --length
This option has been present since the introduction of nbddump (commit
c4107b9a, v1.13.4), but was undocumented unless you read further into
the man page. Mentioning it in --help and in the synopsis is useful,
and will set the stage for adding other options that should be
documented.
