Log:
  MFC 362290:
  
  Clean up fstat.1
  
  - Sort options in the list & indent for readability.
  - Pet linters
    - Use "\(em" instead of "--"
    - Remove Tn macros
  - Use Ql instead of Dq Li
  - Add arguments to the -M, -N, -p, and -u options in their descriptions.
  - Use Sy instead of Li for field names. Li is deprecated, and Ql makes no
    sense here.
  - Replace a literal block with a list for the table of special names
    related to FD.
  - Use Ql instead of ``X''.
  - Add a dot after etc.
  - Reference fuser(1).
