[Bug-XBoard] autosaving broken in xboard 4.2.7 for linux

[Peter Stein]

Hello,

By default without any "saving" options xboard autosaves games in the 
current working directory in a "game.xxx" format. However there is no 
way to autosave games in another directory as the "-sgf" (save game 
file) option is ignored.
Thanks.

Sincerely,

Peter Stein
