I just took a look at what you built on top of this topic (55ccf85)
instead of the bit quoted above. I also found it ugly not to pass the
explicit flag all the way down to the point-of-use. I had a nagging
feeling that the original did not do it that way for some good reason,
but looking at your patch, I cannot fathom what that reason could
possibly be. So it looks good to me.

PS It would have been nice to see the patch on the list for review. I
   only noticed it because it hit 'next', and had a minor conflict with
   my patches in the area.
