This test was about the "From " in the body of the message getting prefixed
with a ">" character, which it did.
I've been wondering how did it came. While the message I'm replying to was correctly
unmunged[*], that message with the >From was not. I tried removing the > but
couldn't verify the message just the same. I couldn't understand why.
It's a relic of the old mbox format, where each message started with a line
with "From ", so the message bodies that had that got a > prepended to them so
that they wouldn't start a new message. This shouldn't really be happening on
modern systems for new messages, though, since there are much better formats
than mbox available today.
From me, anyway, software puts a space in front of a line starting with "From
", before signing.
