[PATCH v4 0/1] config: allow giving separate author and committer idents

All,

this implements the changes requested in v3 of this patch:

- removes an extra comma from the enum
- reworks the logic for config handling so that the author and committer
  variables are handled along with the user variables.

Please review.
