git cherry doesn't list a merge commit

["Tajti Ákos" <akos.tajti@intland.com>]

Dear List,

I have a question/misunderstanding about 'git cherry'. The scenario is 
the following:
I have two repositories (two forks of the same parent repo): A and B. I 
created a commit in A, then pulled B to A and finally made an other 
commit in A. This resulted the following commits:

-----
commit f6afabb0a734843d5d122b612f0701d27b178e42
Author: akostajti <akos.tajti@intland.com>

commit 4ec4d59f632b93456890db139125419d16a10807
Merge: a73e884 2a483e8

Merge branch 'master' of http://localhost:3180/git/first-60-project

commit a73e884d2dadf29898c2d6b665ed79d352422d26

Now If I fetch B to A and run 'git cherry FETCH_HEAD master' I get only 
two changeset ids:
+ a73e884d2dadf29898c2d6b665ed79d352422d26
+ f6afabb0a734843d5d122b612f0701d27b178e42

However, the manual of git cherry says:
"*Every* commit that doesn’t exist in the <upstream> branch has its id 
(sha1) reported, prefixed by a symbol. The ones that have equivalent 
change already in the <upstream> branch are prefixed with a minus (-) sign"

In my understanding this means that the merge commit 
(4ec4d59f632b93456890db139125419d16a10807) should be also listed by 
cherry, because it doesn't exist in the upstream. Am I doing something 
wrong? How can I ge git cherry work as I expect?

Thanks in advance,
Ákos Tajti
