 Systematic behavior validation of most possible cases
 =====================================================
 
 This section tests most of the possible combinations of revision states and
 working directory states. The number of possible cases is significant but they
 but they all have a slightly different handling. So this section commits to
 and testing all of them to allow safe refactoring of the revert code.
 
 A python script is used to generate a file history for each combination of
 states, on one side the content (or lack thereof) in two revisions, and
 on the other side, the content and "tracked-ness" of the working directory. The
 three states generated are:
 
 - a "base" revision
 - a "parent" revision
 - the working directory (based on "parent")
 
 The files generated have names of the form:
 
  <rev1-content>_<rev2-content>_<working-copy-content>-<tracked-ness>
 
 All known states are not tested yet. See inline documentation for details.
 Special cases from merge and rename are not tested by this section.
