1. I looked at the "index" as a staging area for _changes_ not files
themselves. So where 'man git-rm' says '--caches ... remove[s] the
paths only from the index, leaving working tree files.' I took it to
mean that it removes the changes on those paths, rather than staging a
new "path deletion" action for a later commit.
The index is a full snapshot of "what will be commited". The
interesting parts of the index are usually the ones which differ from
either HEAD or the working tree, but the index do contain everything.
