Pattern: Pack clues for each row more closely together

Rather than centring each clue in an imaginary box, put equal amounts of
space between them (using space characters) and then right-align the
whole string.  This makes for more efficient use of space, and I think
it also looks better when there are two-digit clues.

This does introduce a rather grotty (if large) fixed-size buffer for row
clues.  Probably the row clues should be pre-formatted into a string
when the puzzle is set up.
