When the user selects a number of files they would typically expect to be able to act on that selection, such as by including those files into the next commit. So we now have a menu option under the Commit menu that lets the user include only the selection, rather than everything. If there is no selection but there is a file in the diff viewer than we consider that to be the selection (a selection of 1). Unfortunately we don't disable this option yet when there's nothing selected to include, but this is probably not a big deal as there are very few situations where there are no selected files.
