The reason for having 'version' in the menu and not 'revision' is that
the revision number of the previous version of the file can be any
number before the current revision. Revision numbers in SVN are
global, thus with each commit that new revision number applies to all
files in the entire repository.
Given that most files do not change between commits, the diff between
HEAD and HEAD -/- 1 ('diff with previous revision') is empty: files
are identical. 'Diff with previous version' will determine the
revision number of the most recent commit that actually modified the
file and then create a diff between that file and the current BASE
