   short-hand, e.g. if you have this in your $HOME/.gitconfig:

        [pretty "robin"]
                format = "commit %H%nAuthor: %an <%ae>%n..."

Afiak there is already support for this.. from "git help config":

Yup.  But before the first bullet item is done, it cannot be used to
replace the built-in hardcoded formats with a built-in set of default
configurations.

 * (optional) Replace the hardcoded implementations of pretty
   formats with short-hand names like "medium", "short", etc. with a
   built-in set of pretty.$name.format using the configuration
   mechanism.  But we need to make sure this does not hurt
   performance for common cases.

This part obviously hasn't been done, I don't know if any particular
format is not expressable today by the pretty syntax or not..

One that we know we cannot is the nice conditional one Robin wants.
I do think it is a reasonable thing to have.
