def get_status_revisions status_entry
  # the printing revision in svn (svn diff -r20) are confusing, but this
  # is what it looks like:

  # when a file is added locally
  #     the revisions are (0, 0)
  # when a file is modified:
  #     if the file is modified in other revisions since givenfromrev
  #         the revision is (most recent rev, working copy)
  #     otherwise
  #         the revision is (previous revision, working copy)
  # when a file is deleted:
  #     the revision is (given from rev, working copy)

  # okay, summary #2:

  # if a file is modified,
  #     if the file existed at fromrev
  #         it is compared with fromrev
  #     else
  #         it is compared to BASE
