i added this test as it's more "unit" compared to the final formatting, which
might be affected by all sorts of other things (column limits, bin-packing
etc.). whereas this one particularly checks that we provide the "relevant"
signal only in the case we care about.
we can't really have it in the FormatTest, as this is the file that has
utilities for asserting on annotations of tokens.
if you think that isn't useful, i am happy to drop it completely, but i believe
this is valuable for the reason i mentioned above.
