If I encrypt a file and change the last extension ".gpg" to ".GPG" or ".PGP" in the process, I expect the same behavior as if I had not changed the extension or changed it to ".pgp". That is that ".gpg" or ".pgp" are stripped, leaving the extension before them as last extension, e.g. ".txt":
Instead the file is classified as renamed even though only the ending was changed and “.out” is added to the filename:
Note that in contrast to the first case, the file is now classified as "renamed" although only the last extension changed.
