Comment (by desrosj):

 [attachment:"45299.2.diff"] is a patch that combines the two changes and
 applies to the 5.0 branch.

 Also, set up a [https://travis-ci.org/desrosj/wordpress-
 develop/builds/454692121 test build on Travis]. The changes are not
 causing any test failures, but I doubt there are tests that would trigger
 this specific edge case.
