Upstream changes:

1.6.4 Wed Feb 16 07:43:28 CST 2005
  - I screwed the pooch on 1.6.3, blatant typo pointed out to me by matrix200
    guess I forgot to run make test before releasing.

1.6.3 Sun Jan 30 20:53:22 CST 2005
  - arrg, I fixed get_quotaroot incorrectly and didn't test it. It should
    have used the same regex as get_quota instead of what I did. Thanks
    Franscesco for pointing out the error (again).

1.6.2 Sun Jan 30 10:33:50 CST 2005
  - bug report from Francesco Gennai, get_quota and get_quotaroot improperly
    handling folders/mailboxes with spaces
    patched both with a regex to handle the data extraction, should work now.
