Comment (by mcs):

 Replying to [comment:28 gk]:
 > mcs/brade: Oh, and don't let my above comment stop you from debugging if
 you have the time and energy for that. :) Or let me know about some
 shortcuts I could take to figure out what is going on.

 OK. The thing that does not make sense to me is that on 2019-08-29 Kathy
 and I were able to successfully run an update with our own Windows build
 after we replaced all of the `%s` format specifiers with `%S`. That test
 was interactive (using our own mar file and update server, and with tor-
 browser just patched for our own signing certificate and to use a
 different `app.update.url`). If there was another mingw-w64 bug we should
 have encountered it during that test.
