All went well

So far so good.

$ git merge --no-commit -s ours fnc/master i00f000/master
i99f000/master include/master l00m000/master l01f000/master l02f000/master l03f000/master l06f000/master l90z000/master leerpl/master mutbev/master prtabel/master rpt/master tabellen/master zoomen/master Automatic merge went well; stopped before committing as requested

$ git commit --amend
fatal: You are in the middle of a merge -- cannot amend.
$ git status
# On branch master
nothing to commit (working directory clean)
When I start git-gui, it still shows a long commit message:
Merge commit 'fnc/master'; commit 'i00f000/master'; commit 'i99f000/master'; commit 'include/master'; commit 'l00m000/master'; commit 'l01f000/master'; commit 'l02f000/master'; commit 'l03f000/master'; commit 'l06f000/master'; commit 'l90z000/master'; commit 'leerpl/master'; commit 'mutbev/master'; commit 'prtabel/master'; commit 'rpt/master'; commit 'tabellen/master'; commit 'zoomen/master'
All other areas are clear
