I misremembered! I went and looked at the code, and EBDB does clobber,
but "inside" the `message-tab' function: it pushes a value onto
`message-completion-alist' which matches all the mail-message type
headers, so that `message-expand-name' never gets called.

The whole `message-tab' machinery is awfully complicated for something
that, in the end, just forces you to choose between BBDB and EUDC.
