Hi,
I send the same "-U/--user-agent" patch here as earlier, but mime
attached this time.
I'm sorry for posting it as a separate thread -- I usually interact with
the list via Gmane, so I could post this as a followup only if I had a
newsreader which can do mime attachments. It's not the case now, and
installing/configuring one would be more hassle than it's worth for.
