I can pin this down at r1.26 of su.c
(Mon May 25 03:34:52 1998 UTC (3 years, 2 months ago) by steve)

Prior to this date only appearance in /etc/group was considered.

The change occurred in response to PR bin/6696

Like terry, I prefer the semantics whereby the users primary
group is considered. Three years of precedent should be sufficient
to have this change to pam_wheel.c, I hope, before PAM use in su
is MFC'd.

I have just entered a PR on this.
