// other stuff in their TypeNames) (see commit 4bc7d1c76f97d0)
// b) When we write the string here, for some reason it causes a
// transition between steppable pipelines, and the PS default
// formatter wants to put in an extra newline at the format start and
// another at the format end.
//
// Fortunately, it seems easy enough to workaround by sending a different type
// of object down the pipeline.
//
// (I wonder if it might have been specific to the particular commands I was
// using to test, like "uf blah!blah | fl", or symbols | fl, because of how
// their formatting was done.)
