[Haskell-cafe] Pretty-printing peg solitaire boards

Hi, I'm trying to pretty-print (with Text . PrettyPrint . HughesPJ) a set of peg solitaire boards. No matter what I try, I always get this: 00# 00# 0000#00 0000000 0000000 000 000 : 00# 00# 0000000 0000000 0000000 000 000 but what I really want is this: 00# 00# 00# 00# 0000#00 0000000 0000000 : 0000000 0000000 000 000 000 000 000 What I'm I doing wrong? When I have two boards a,b::Doc, I'm composing them with a <+> colon <+> b and rendering them with just 'render'. Should I try something else? Thanks, Maurício
