This looks to be working fine, but let me see if I've got this
straight ...

in this case, %{?-v*} doesn't just expand to the argument to -v, but
also passes the "-v" to %kernel_variant_posttrans ?

i.e. I'd expect it to be something like:

%{expand:%%kernel_variant_posttrans %{?-v:-v %{-v*}}}\

I know spec file syntax is bizarre, but does anyone have a sensible
explanation for this behaviour?

Cheers,
Mark.
