Done. Finished the small shell script I created in July 2020. Put it in place
at moin.cgi. It puts up a redirect page and redirects after 5 seconds to the
request page at wiki.

The page has headers set to prevent caching. May need to revisit that, but I think
a non-cached response will work. I set it to non-cache to clear debugging env var dump
from the caches. I have since removed debugging, but the no-cache setting should clear
anything left in the sourceforge cache.
