Hmph.  Is it gmane who is munging these lines?

The other copy of this message I received in my mbox (which I read
in the same MUA) does not seem to have this corruption, and I do not
expect vger.kernel.org to do this kind of munging without getting
yelled at by the kernel folks.

Anyway, thanks; I'll take a deeper look once I got a chance to.
