> We probably need a `short_node` function which only shortens strings that look like a commit SHA (`/^[0-9a-f]{40}$/`)

Maybe use `{12,40}` instead of `40`.

But maybe better is to use git commands to know if some revision info is a reference or a sha git revhash.
For example:
```
# This errors if ref isn't a valid reference. With --quiet it doesn't output anything.
git show-ref --verify --quiet <ref>

# This errors if ref-or-sha isn't a valid reference or a valid sha in this repository
# Otherwise it prints the sha for this ref.
git rev-parse --verify <ref-or-sha>
```

Maybe there are others I don't know, or some attributes for these commands that could be more useful.
Hope this helps!
