There's yet another place as well, but its only related to obsolete pre-1.5
stuff that has very little use anymore.

Its guess_remote_head of remote.c (checked v1.7.2-rc3+). Additionally, it appears that if master doesn't tie for exact match, then first ref in lexical order is choosen (if master ties for exact match, then it is chosen).

Additionally, it appears that if exact HEAD symref information is available (not all protocols support that), then that is choosen with no guessing.
