Hello Ulrich,
I debated where to place the fix since this is not a public documented
function. At least I could not find documentation for the function. I
decided to go with the location and type of return previously presented
by the function. If the author/maintainer desires the other approach and
would like a tested patch, I would be happy to do it.
