Adding the appropriate variant of

  DEBFULLNAME="Loïc Minier <lool-nospam-dooz.org>

to your aliases should resolve most of your request, since DEBFULLNAME
is one of the few environment variables we honor.

There was a specific choice at some point in devscripts' history not to
honor configuration from the environment except for a select few items
(like DEBFULLNAME).

It's been that way, as far as I can tell, the entirety of devscripts'
history, so I'm hesitant to change that, especially just for one script.

Hopefully at least the DEBFULLNAME information helps.
