@alexjh thanks for this. To the best of our ability, we cannot see where this method is used, so rather than merging this PR we'd rather remove this function entirely.

Before we do that, can you tell us if you actually use this function somewhere, or were you just cleaning up quoting because you saw it was potentially a problem?

[alexjh]

This was just a drive-by clean up that I noticed when tracking down something else. :) Removing the function would be fine with me.

Great, thanks. We will remove this function instead of merging this PR.
