I think it may be better to only display the line when the lines above
it contain legitimate mail headers. Maybe make the regexp in
`rfc822-goto-eoh' more strict?

In Bastien's example, the first line of text doesn't match neither the
regexp in log-edit-font-lock-keywords, nor any in
message-font-lock-keywords.
