I’ve managed to create a bad filename using some script. The file name is “iredir-<<<<<<< HEAD?0.5.2n.tar.gz” (without the double quites and the ‘?’ is actually an ASCI LF (line break)).

When trying to delete the bad file using ‘d’ and ‘x’ in dired of Emacs 27.2, it fails like this:

It asks:

Delete iredir-<<<<<<< HEAD

0.5.2n.tar.gz

  -rw-r--r-- (yes or no)

And when entering “yes” it replies with “Deleting…done”, but the file is still there
