That seems to be the case: as I read the code, it is writing only the text.

I think it is a bug.  (I am puzzled why it was overlooked, aside from
noting that putwin is not often used...).

On the other hand, I do not like the implementation (but have had no
compelling reason to revise it), because it relies upon the binary
layout of the window structs.  For instance, you could not transfer
between normal/wide libraries.  (I'm not keen on starting a new development
task at this moment because I was trying to wrap up things for a release,
but I'll see what I can do).
