This mangled header caused TBird's reply-all to do the following:

I've never used the feature, but AIUI, this "unlisted-recipients"
directive in TBird turns all subsequent CCs into BCCs.

Actually, upon further inspection, a BCC header isn't the issue, because
there's not one, just the mangled CC:

Illegal-Object:	Syntax error in CC: address found on vger.kernel.org:
	CC:	unlisted-recipients:;Linux-RAID [off-list ref]
					     ^-missing end of address

vger simply replaced the broken CC header with a syntax error message.
Thus a reply-all to this message will simply go to the sender and the
non-broken CC list, i.e. to me and to Roberto, not the list.

Regardless, the root of the problem lay with Roberto or his MUA for the
original mangled header.
