Subject: [PATCH] 2008-02-09  Marcus Brinkmann  <marcus@g10code.de>

	* gpg.c (main): New variable default_configname.  Use it if
	save_configname is NULL (can happen if default configfile does
	not exist).  Move default configname determination to ...
	(get_default_configname): ... this new function.
