Well, there were regression tests for blobs for a long time, but they
carefully cleaned up their mess. It was only in 70ad7ed4e that we
made them leave some blobs behind.
I took a quick look at back-patching that commit, but the test would
need to be rewritten to not depend on features that don't exist
further back (like \gset), which likely explains why I didn't do it
at the time.
