Format of meldinit strings:

	tag/score/cards/incompatabilities/name

    tag
	A short name for this meld.  Spaces are ignored.  Must not be
	of the form T[cdhs]; see the incompatibilities list for the
	reason.

    score
	This meld's score. Spaces are ignored.

    cards
	A list of cards making up the meld.  Each card is
	[9JQKTA][cdhst], where T means 10 and t means whichever suit
	happens to be trumps.  Spaces are ignored.

    incompatabilities
	A list of tags of other melds that are incompatible with this
	one, in the sense that a card that has participated in this
	meld cannot form part of any incompatible meld.
	Incompataibilities should be symmetric; if X is incompatible
	with Y, Y should be with X too.  Every meld is automatically
	incompatible with itself; these don't need to be listed.
	Space-separated; spaces otherwise ignored.  As a special case,
	T[cdhs] means that the meld is incompatible with trumps being
	the specified suit.

    name
	A long, human-readable name for the meld.  May contain any character;
	it begins with the first non-space after the fourth slash.
