Subject: SAN problem with Crafty's wall.pgn book

Fellow Programmers:

In working with Crafty's opening book PGN file wall.pgn, I noticed an
error in SAN in one of the games.  (There may be more than one; this is
the first.)  It shows up at line 3,864,317 in column 47; it is a pawn
capture "exf1" but has no promotion indication.

Have other PGN readers choked on this?  If not, then they should have.
It is incorrect to assume a promotion to a queen.

Anyway, having nearly four million lines of good PGN before the first
problem is still pretty good.
