rewriteutil: say how many commits would become orphan if commit is rewritten

This copies the message from the evolve extension, but modifies it a
bit to work with the grammar (in particular with the use of "change
branch of" as `action`). I don't know why it doesn't use the same
`_formatrevs()` as for public commmits.
