It's definitely better than before. The current implementation of
pass_if_equal has IMHO one drawback - if it compares multiline text and
there is a difference, it is quite hard to see where.

In my tests for maildir synchronization I use this approach:

  notmuch search tag:inbox | filter_output > actual &&
  diff -u - actual <<EOF
  thread:XXX   2000-01-01 [1/1] Notmuch Test Suite; test message 3 (inbox)
  EOF

Thanks to the usee of diff, I immediately see only the differences.
