+ maint: fix public-submodule-commit to work with newer git
+ * top/maint.mk (public-submodule-commit): Remove excess quoting.
+ We were over-quoting the test arguments, and somewhere prior to

+ which made the test fail, since the unexpanded strings would
+ always differ; using GIT_TRACE=1 confirmed that the git merge-base
