If you remove '--graph', then you can add '--show-linear-break' [1]. Unfortunately these two options do not work together. I think your suggestion to have the '*' be changed to '#' for root commit is a great idea.

In the mean time, I use this trick:

     git log --date=short --format='%C(auto) %h% [%<(2,trunc)%p] ad%d% s%C(green)% aE'

This adds the abbreviated parent hashes (%p) but truncated to 2 characters ([2], [3]). So the brackets will be empty for root commits.

Cheers,

Philippe.
