Fwiw this change appears to have crept in when the patch was merged.
Ironically while most of us have been complaining about patches not being
widely visible and tested outside of CVS in this case we perhaps suffered from
the opposite problem. The patch was fairly heavily tested on this end before
it was posted and I'm not sure those tests have been repeated since the merge.
