Support alternative formatting for large tables

[immoh]

In order to keep lines short (e.g. below 120 chars) some tables could be formatted with alternative formatting that would format each cell to its own line, adding extra line break between rows:

tabular
  (fact "The rules of Conway's life"
    (alive? ?cell-status ?neighbor-count) => ?expected)
  ?cell-status
  ?neighbor-count
  ?expected

  :alive
  1
  FALSEY

  :alive
  2
  truthy

  :alive
  3
  truthy

  :alive
  4
  FALSEY
  
  :dead
  2
  FALSEY

  :dead
  3
  truthy

  :dead
  4
  FALSEY)

User should be able choose which formatting to use either by supplying option to main function or configuring it per table somehow (tabular metadata?).
