Revert changeset 120aa5fc7ced1bf765b4f025f5a3a138cd87f49e.
I inadvertantly used "hg import" on a message I saved, expecting it to do
the right thing, but instead it made the commit look like I authored it,
and filled the description with the email header.
Changeset 737f9b90c571b3991f7e35dc846e7ef38a475cfe contains a guard
against "hg import" doing this again.
