I don't really like the extra argument; aggregate functions should
almost never have to care about whether they're being called as window
functions rather than aggregate functions. And if it does care, I
don't see why this is the appropriate function for it. At the very
least the function should accept NULL for the "iswindowagg" pointer to
avoid useless variables in the caller.

So for this and the regression test problem mentioned in the other mail,
I'm setting this back to "waiting on author".
