Can we have a small common helper library (e.g., repo-info.c at the
top level) shared between this code and builtin/rev-parse.c so
that we have only a single implementation of 'cdup'?

The same comment applies to all the other features that duplicate
implementations from rev-parse and elsewhere in the repo-info file.
