I don't believe supportnodes.h has any business having any code that's
related to actual implementations of the support request type.  If we
were to have such a definition then I think it would belong in
windowfuncs.c.  I'd rather see each implementation of the support
request spell out exactly what they mean, which is what the patch does
already.
