   Ok, since after this refactoring the changes needed for my tests are
really simple, I just went ahead and committed them. They can easily be
reverted in case I missed something.

   I have not removed --ignore-config as I do not know what it is being
used for. As far as I can see, nothing in Boost or Boost Build uses it
and that Boost Build documentation mentions it only superficially.
