Ok.

Let's try to keep the changes minimal and simple.

Your original approach with __filename_create() looks reasonable, if
we then just clean up the end result by making putname() ok with an
error pointer.

The odd conditional putname() calls were the main issue that made me
go "this is just very ugly and confusing"

How do the patches end up looking with just that cleanup (and some
clarifying comment about the very odd "out_putpath" case it had?)
