There appears to be three sets of constraints here:

1) The code author/maintainer wishes to use an email address that stays
   valid across employers (name@xxxxxxxxxx is another example of this),
   which is a way to stay reliably reachable over his entire career,

2) The employer requires attribution for tracking copyright ownership.
   This is typically done by requiring employees to use their corporate
   email address for code submissions, which is incompatible with (1).

3) Adding the employer in the form "First Last (Employer)" as a
   work-around creates separate author entries in the git shortlog.

I see a few possible solutions there:

- We can teach git to know about this "First Last (Employer)" formatting
  and combine duplicates.

- We can move the employer attribution to the email address instead,
  e.g.: name.corp@xxxxxxxxxx or name+corp@xxxxxxxxxx (or whatever we
  figure out looks OK).

Thoughts ?

Thanks,

Mathieu
