Right now, all the files are still there in the working tree - changes
to them just aren't reported, shown, committed, etc.

Ultimately, it would be good to save disk space by only updating the
working tree (from the branch) *if* an initial view is given to branch
and checkout. That's not supported yet.

Agreed. I'm gradually expanding the "Open Issues" section to cover some
of trickier design questions and my thoughts on future directions. My
first goal though is to get the core functionality working and landed.
