* gpgconf-comp.c (hextobyte): New function.
	(percent_deescape): New function.
	(get_config_pathname): Percent deescape pathname if taken from
	option (default) value.  Use default value only if it exists and
	is not empty.  Use empty string otherwise.  Don't include leading
	quote in pathname.
	(change_options_program): Percent deescape string before writing
	it out.
