Sometimes it is asked on the list how to revert selected path in
the index from a tree, most often HEAD, without affecting the
files in the working tree. A similar operation that also
affects the working tree files has been available in the form of
"git checkout <tree> -- <paths>...".
By definition --soft would never affect either the index nor the
working tree files, and --hard is the way to make the working
tree files as close to pristine, so this new option is available
only for the default --mixed case.

* I haven't looked at Documentation/git-reset.txt recently. It
most likely needs not just addition to describe this new
format, but more a heavier rewrite similar to what we made to
git-commit documentation recently.
