Lack of clarity in description of set-match-data in elisp info page.

[Alan Mackenzie]

The description of set-match-data on the elisp info page "Entire Match
Data" states:

     This function sets the match data from the elements of MATCH-LIST,
     which should be a list that was the value of a previous call to
     `match-data'.

This is unclear:  Better would be whichever of the following alternatives
is the case:

(a)  This function sets the match data from the elements of MATCH-LIST,
     which should have the same format as the value returned from
     `match-data'.

(b)  This function sets the match data from the elements of MATCH-LIST,
     which should be a list that was the value of a previous call to
     `match-data'.  Note that `match-data' changes the internal state of the
     lisp-machine, so using a value of MATCH-LIST which was not returned
     from `match-data' will not work, even if it has the correct format.
