Ah, I thought I'd even tried that, but I must have not rerun the test
correctly.

Not here - this is simply the amount which is added to the wdf for
each occurrence of a particular term.  OTOH, OP_SCALE_WEIGHT allows
a floating point scale factor because it's scaling the weight
returned by a term (which is a Xapian::weight).

So it's a slight incompatibility (presumably XS Search::Xapian accepts
this) but it doesn't actually stop you doing anything you could actually
do before.

I'll see if this can be accepted.
