I think these functions are just copied from other dltests. Chris

You would want to look at the purpose of the test, and how similar
tests are structured. Was it a mistake not to call these functions? Or
are they not needed for this test?

It may be helpful to avoid html markup in mailing lists. We don't
filter it out, but some mailing lists (and clients) may.
