Description

Please describe your pull request.

NOTE: All patches should be made against master, not a maintenance branch like
3.1, 2.5, etc. That is unless the bug is already fixed in master, but not in
that version series.

If it fixes a bug or resolves a feature request,
be sure to link to that issue via (Fixes #4412) for example.
