Add leading and trailing pipes to tables in readme.md (#394)

A rendering of the “Terminal support” table was broken in `README.md`.

The [new GitHub's parser][1] seems to handle differently the leftmost empty
table cell if it has no leading pipe (`|`):

* if it's in the middle of the table, the whole row shifts to the left
  (the second cell becomes first, third takes place of the second, etc.)
* if it's the table's last row or all rows after it also have only whitespace
  and no leading pipe, they are parsed as a new block element
  (the code block, because of leading whitespace)

Also, new spec [recommends][2] adding leading and trailing pipes for
_“clarity of reading”_ and to avoid parsing ambiguity. Both currently existing
tables were updated to follow this advice.
