Let me try: i'm copying below the two lines quoted above with a single >
and no spaces:

and now here's a l o o o o o o o o o o o o o o o o o o o o o o o o o o o
o o o o o ng line... which i am afraid got auto-filled without
trigerring the bug... so i guess we must be doing something different,
but i don't see what.

as i mentioned in my original report, this bug is annoying in that i can
paste the exact content of a buffer where it's happening into a second
one in message mode, and the bug won't be triggered in the second
buffer, so it seems to very sensitive to context.

anyway, Katsumi, since you have a couple of cases where it's happening
for you, perhaps you could answer Eli's question and tell him what's the
output of C-h l when you manage to reproduce it?

thanks!
