Reformatting multi-level quotes

[Anders Melchiorsen <postmaster@and.nospam.kampsax.k-net.dk>]

I have a problem formatting quotes when they are nested. Gnus (at
least with my configuration) adds "> " in front of quotes. This gives
a quote like this

> > Old stuff
> > is here
>
> Newer stuff
> is here

and when I try to reformat the "Old stuff" quote (by using M-q,
fill-paragraph-or-region) I get (notice the extra > in the middle)

> > Old stuff > is here

However, if the quote is like

>> Old stuff
>> is here

I get the proper

>> Old stuff is here


So why is Gnus by default creating quotes that cannot easily be
reformatted? I guess I can change the quote prefix string somewhere,
though. Or perhaps I should use something instead of
fill-paragraph-or-region to reformat quotes?

Whatever. I just found it odd, and wanted to report it.
