Subject: [PATCH] Fix crash on loading garbage game file

XBoard crashed when a game file contained a PGN game result before
any valid game start, because data would be written in a game-list
node that did not exist yet. This would occur frequently when garage
was read; basically any asterisk in the data would do it.
