It's standard for certain applications (like mail readers) to enforce a
separate umask, which is what Gnus does via `mm-save-part-to-file'.
However:

As Stefan points out, it's a bug for the url library to use this rather
high-level library to save stuff.  And the url library has no reason not
to heed the umask.

Anyway, this isn't a Gnus bug, so I'm reassigning it back to Emacs.
