WIL diagnostic level 2 not working

            if (failure.pszFile != nullptr)
            {
                dest = details::LogStringPrintf(dest, destEnd, L"%hs(%u)[\\%hs!%p](file://%25hs!%25p): ", failure.pszFile, failure.uLineNumber, failure.pszModule, failure.returnAddress);
            }
            else
            {
                dest = details::LogStringPrintf(dest, destEnd, L"%hs!%p: ", failure.pszModule, failure.returnAddress);
            }

The code says “Well, if you don’t provide a file name, then I’m just going to log the module named and return address and not bother with a line number.”

Having said that, level 2 is pretty worthless, so maybe it should be removed with a #pragma error if that level is chosen.

Start from the shown C++ diagnostic-formatting branch and trace how diagnostic level 2 reaches it. Determine the intended level-2 behavior from nearby diagnostic handling, then verify that the chosen behavior no longer silently omits the line number or leaves level 2 unusable; add or update the relevant diagnostic coverage if one is present.
