BIG MAN pushes around corners; at a fork the pushed wizard chooses

Eric, a giant on his first turn, could only shove a wizard in a
straight line: the engine shoved in the giant's own direction or
refused. The FAQ says otherwise — "If Big Man pushes someone to an
intersection, then the other player gets to decide which direction to
go." Now a pushed wizard leaves by any open side but the way the giant
came. One open side is taken. Several are theirs to choose: the stride
hangs in a pushPending window like the Ward's, the pushed wizard
answers with pushChoice (a dialog offers the ways; an automaton steps
out of the giant's line), and the stride resumes with the answer — a
blinded giant's roll is not rolled twice.

Rounding a corner was a refusal before, so every game may do it now.
Only the case that used to resolve — straight ahead open — keeps its
old reading in games dealt before rev 15; from rev 15 the pushed
wizard chooses there too. Tests pin the corner, the fork's window and
its refusals, and the older reading; 84 ledgers replay.
