Can we separate authors with ; instead of \n please?

jml, lifeless and I were talking about a search language yesterday
so users can doing something like ...

  bzr log -s committer=me:

With this in mind, I'm wondering whether it would make searching
authors easier if they were separated by ; instead of a newline
internally.

Assuming multiple search terms are or'ed together, I'd like to search
for revisions where X and Y paired using ...

  bzr log -s authors=X;Y -s authors=Y;X

If we keep the newlines, it would probably look something more like ...

  bzr log -s "authors contains X" -s "authors contains Y" --match-all-searches

Anyhow, if we're going to change this, let's do it before 1.13RC ships,
i.e. TODAY!

Thoughts?
