When manually resolving directory conflicts isn't a feature

This feature already exists: “bzr clean-tree --ignored”.

Running that before every switch would help workaround this problem, but:

  a) it shouldn't be necessary,
  b) it's wasteful; for directories that are unchanged in the branch being
     switched to there's no need to delete anything, and it will cause the next
     “make” invocation to be slower (whether we are taking about .pyc files, .o
     files, or .aux files...).
