[Rpm-maint] [rpm-software-management/rpm] BUG: $1 and $2 arguments passed to scriptlets go awry for renamed package upgrades (#474)

[Jeff Johnson]

>From https://stackoverflow.com/questions/48070042/how-to-detect-upgrade-when-an-rpm-that-obsoletes-another-rpm-is-being-installed

The practice of adding a Provides: oldname to satisfy dependencies when renaming a package has unintended consequences for the package count arguments passed to scriptlets: the count is based on the package N, not the Provides: oldname.

Rather than trying to detect package renaming -- a rather rare event -- and adjust the arguments passed to scriptlets, I'd suggest that the better fix would be to devise a means to differentiate between erase-while-upgrading and erase-while-removing that is by far the most common need to test package counts.
