I think it'd be a bit more intuitive is this was an option, like
`--base-tree=` or just `--base=`.

One question that comes up naturally in this context: when I have a base
tree, how do I remove entries from it?

Presumably the same way how you remove entries with "update-index --index-info"?
I.e. mode=0 entry in the input would serve as a signal to remove the
path?
