[PATCH v3 0/6] Support triangular workflows

After Jonathan's review of [1], I've decided to pick two changes to apply in this iteration:

1. [1/6], [5/6] and [6/6] now use the return value of
   git_config_string(), hence handling configuration errors properly.
   I consider this a major and important improvement.

2. The commit message in [4/6] has been augmented with a small
   example.  This is mainly a nit, as full-blown examples are already
   present in the next two patches in the series.

Thanks.
