Thinking about this more, buffer-local variables have their own
complications:
- You need an buffer open, inside the given directory tree, to get their
values. The project-find-functions API just passes in DIR to get a
project instance. There might not even be a buffer open in that directory.
- If a user tries to set their values in init.el, that won't end well.

You can't reuse the variables. There might be several project instances
open at the same time.
The best bet seems to be to store them in the project file, which a
project backend reads and saves to the project instance's slots.
Not sure what this means for the VC project backend. Git allows storing
arbitrary key-value pairs in .git/config via 'git config', but that
isn't true for every VCS. Bazaar doesn't, AFAICT.
