I don't know what future breakages Nelson wants to protect his code from, but this change breaks the test for union merge in t6026-merge-attr.sh.

It isn't that the test script expects no space after the conflict marker, but with Nelson's patch, the union merge no longer works.

I request this patch to be dropped.
