./t3310-notes-merge-manual-resolve.sh broken on pu under Mac OS ?

["Torsten Bögershausen" <tboegi@web.de>]

I got 2 failures on pu under Mac OS, (Linux is OK)
I did some very basic debugging, it seems as if grep doesn't find
a needed string.
Does anybody have an idea here ?


--------------------
Failure 1:
Add some debug code:
git diff

-       grep -q refs/notes/z merge_commit_msg &&
+       echo >&2 before grep &&
+       echo >&2 before cat &&
+       cat >&2 merge_commit_msg &&
+       echo >&2 after cat &&
+       grep  refs/notes/z merge_commit_msg >&2 &&
        # Merge commit mentions conflicting notes
+       echo >&2 after grep &&

------ run the test:
debug=t verbose=t   ./t3310-notes-merge-manual-resolve.sh 2>&1 | less
-------- get this output:

before cat
Merged notes from z into refs/notes/m
