Namely, Philippe felt it important to
have one patch that completely backed out two or more of my previous
patches, followed by a patch that incorporated a useful part of one of
those patches.
Did I do that? My original big/unique patch did indeed remove your fix to one of the tests in C03traps.ztst and at the same time added an equivalent but different fix. I realized this only after sending my original patch. My split patches no longer do that; patch-01-revert-mistaken-errexit-patches.txt no longer reverts your fix. I'm not aware of another of your changes that I revert in patch-01-revert-mistaken-errexit-patches.txt and add back in one of the later patches. Did I overlook something?
