huh, I thought git name-rev prefers old[1] refs (similar to describe
prefering newer).

$ for rc in 1 2; do git name-rev --refs=refs/tags/v2.6.39-rc$rc 69a07f0b1; done
69a07f0b1 tags/v2.6.39-rc1~79^2~31^2~4
69a07f0b1 tags/v2.6.39-rc2~3^2~43^2~4

I would prefer the v2.6.39-rc1 name even though it's nearer[1] at
v2.6.39-rc2.

If it should stay as is, what is the best way to find out the oldest
tag?
 
Best regards
Uwe

[1] as in minimizing

	git rev-list 69a07f0b117a..$ref | wc -l

(v2.6.39-rc1 -> 21281; v2.6.39-rc2 -> 21608)

[2] as in minimizing the number of traversing a parent link.
