Since quite some time, I wanted to have a way to git-rev-list just the 
revs between commit1 and commit2, i.e. all commits which are ancestors of 
commit2, and which have commit1 as ancestor. With this, my task would have 
been more than simple.

Nope. Was a merge.

That outputs too much. I really wanted to find just the commit which 
removed the function, in order to know where the code was moved to.

ORIG_HEAD would not help, because that commit is not an ancestor.

... and it will say

Sorry, I am too tired now to investigate, have been working already to 
long. Tomorrow's another day.

Ciao,
