The *-opts APIs should not be documented in -h output, since they
are provided for backwards compatibility only.

The others (list provided below) I believe are all aliases, so we
could document them as:

  $ guestfish -h
      Command      Description
  add          alias for 'add-drive'
  add-ro       alias for 'add-drive-ro'
  [etc]
