* Stop manipulating adjustment and hyphenation around a table.
* These could be safely done within the text block, but even that is not
  necessary, since what is in the next block is a single word, so no
  adjustment will take place, and to prevent hyphenation of a single
  word, \% is cheap and straightforward.  So do that.
