Comment 3 for bug 616878

Our use case is /etc in bzr. We don't care at all about having valid
email addresses in the bzr history for these branches. This change is
really problematic for us. We're either going to have to patch it out
or fix hundreds of machines (either by running bzr whoami or setting
BZR_EMAIL with some dummy value).

I understand the rationale somewhat for the more traditional use cases
of bzr (distributed revision control for source code), but we surely
can't be the only users who don't care about the validity of email
addresses and find this an unwelcome change.
