Maybe I am misrecalling things but didn't we have reports from people on
some platforms that single-shot exporting of the environment like this one
does not work for them?

I do not like this very much.  Future improvements of the graph drawing
algorithm (one obvious "flaw" you are exposing by the above is that it has
trailing whitespaces that can be trimmed, and somebody else may be
inclined to fix) would break the expectation this test vector has.

Do you have to compare the topology this way, or are there other more
reliable ways?
