A few of our test projects appear to be broken... If I make a whitespace change to testprojects/src/antlr/python/test/BUILD testprojects/src/java/org/pantsbuild/testproject/targetlevels/unspecified/BUILD or testprojects/src/protobuf/org/pantsbuild/testproject/import_from_buildroot/bar/BUILD I get errors running build-support/bin/isort.sh
