No movement number is spent on a turn that ends at a grab

Room M9QJ, seq 190: a berserker played a 5 to charge a distant enemy,
walked two squares, crossed a treasure, and the gold-underfoot rung —
which outranks everything — ended its actions with six paid moves
unwalked. Before spending a number, the march now checks whether any
goal treasure lies within the free legs: if the turn is going to end at
a grab, the number stays in hand. (Even a charging berserker stoops
for loot; it just shouldn't pay toll first.)
