Local OS (where xxh is installed): WSL Ubuntu 22.04
Destination host OS: Ubuntu 22.04
xxh version: 0.8.12
xxh-plugins installed: WIP Plugin, xxh-shell-zsh

Steps to Reproduce

1. Request xxh to remove itself from the target machine (e.g. +iff or +hhr)
2. If there are any read-only folders containing files in the .xxh directory, removing fails with 'Permission denied'

Fix:
Call chown -R u+w .xxh before removing the files.
