[PATCH] Documentation: clearly specify what refs are honored by core.logAllRefUpdates

[Bert Wesarg <bert.wesarg@googlemail.com>]

The documentation for logging updates in git-update-ref, doesn't make it
clear that only a specific subset of refs are honored by this variable.

Signed-off-by: Bert Wesarg <bert.wesarg@googlemail.com>

The initial justification in 4057deb (Junio C Hamano, 2006-10-08), leaves
the impression, that a blacklist would have made more sense, than the
current whitelist. Maybe we can change this?
