Riku, Efraim, Guix,

I noticed that this commit and the preceding libsass update have 
an incorrect author e-mail addres:

  commit fc4eb87dc45b169e3912c73bbf60cb8ce76b7c7c
  Author: Riku Viitanen via Guix-patches via 
  <guix-patches@gnu.org>

The actual patch posted to guix-patches[0] has two correct From: 
lines.

Does anyone know what happened here?  And how it could be avoided? 
Is the Web interface hiding anything strange about these messages?

Would a git hook to catch suspect addresses be a good idea?

Kind regards,

T G-R
