As promised, attached is a bundle which adds the 'setup-default-ignores'
command. I wanted to write this separately, because I figured it was
more controversial than the previous patch.

All of this can be found at
http://bzr.arbash-meinel.com/branches/bzr/ignores/

And if we want to restore the 0.8 behavior until people setup their
~/.bazaar/ignore file, the patch is:

             if e.errno not in (errno.ENOENT, errno.EPERM):
                 raise
+            ignore_globs = bzrlib.DEFAULT_IGNORE[:]
         else:
             try:
                 process_file(f)

Though we would want tests to ensure that it is working correctly.
