Markdown reader/writer: spacing adjustments in tables.

* Markdown writer now includes a blank line at the end
  of the row in a single-row multiline table, to prevent it from being
  interpreted as a simple table.  Closes #4578.
* Markdown reader does a better job computing the relative width of
  the last column in a multiline table, so we can round-trip tables
  without constantly shrinking the last column.
