As I said in the report, unless I'm mistaken, gnus-tmp-prev-subject's
sole purpose is to be compared with simp-subject.  Since the latter goes
through gnus-simplify-subject-fully, it seems right that the former
would go through it too…

So far the report has not received much attention.  I figure it could be
a good idea to ask this list for feedback: is this an issue someone else
has run into?  Could it be something from my configuration (which I've
posted as a footnote in the bug report)?

Also, I imagine that this list is one of the best places to find people
who can answer the question I asked in my bug report's second footnote:
how would one go about writing an ERT test case for this?


Thank you for your time.
