bzr log --short/--line does not show committer if it has only e-mail

[Alexander Belchenko]

C:\work\Bazaar\qbzr-repo\goffredo>bzr log -r-1
------------------------------------------------------------
revno: 149
committer: <email address hidden>
branch nick: qbzr-unidiff

message:
  add html unidiff header

C:\work\Bazaar\qbzr-repo\goffredo>bzr log -r-1 --short
  149 2007-10-18
      add html unidiff header

C:\work\Bazaar\qbzr-repo\goffredo>bzr log -r-1 --line
149: 2007-10-18 add html unidiff header

In last 2 cases (--short/--line) the name of committer is absent, and therefore output looks strange and bad.

We could certainly switch to just showing the email address if there is no "user" portion.
