I do not think Gnus demiming (that C-u g helps us with) is not
an issue.

Have you tried to look at the article in question?  Inside your
Gnus + news.gmane.org, try typing this:

	j 7 2 6 9 9 <Enter> C-u g

The last two keystrokes are your "C-u g".

And look at the second line in the buffer, that says:

    From: Brian Downing <bdowning-oU/tDdhfGLReoWH0uzbU5w@public.gmane.org>

and weep X-<.

Then scroll down to find Signed-off-by: lines that are similarly
mangled, and weep more.

Maybe you run a much newer Gnus, and Lars taught "C-u g" to
unmangle them.  After all, gmane and Gnus are both his
creations, so it _is_ possible.  But somehow I doubt it.

If there weren't gmane address mangling, a quickest way to apply
a gmane patch to commit is:

	C-u g | g i t  a m - 3 - s <Enter>

	For Gnus uninitiated, it reads: show as raw as opposed
	to demimed (C-u g), pipe the article to the shell
	command (|) that is "git am -3 -s".

But I usually work in batches, so I first C-o (write to file)
the articles to a separate mbox, review and _edit_ them as
needed before running "git am".  And C-o does not suffer from
Gnus demiming, so C-u g is not useful in my workflow.
