    Quick question: I see that there is support for both zero- and
    one-based bitmasks (e.g. ffs() vs. ffz()). Are there technical
    reasons to prefer one over the other? Or is this just a matter
    of preference, or whatever lends itself best to the task at
    hand? (It seems as though I have seen some reference to this
    prevously, but I am unable to find anything in the archives.)
