Arch linux su, sudo and cd errors are notrpinted in red

In the previous trick i used to color stderr, these errors where printed (but su was broken...),
But with stderred, these commands seams to be blacklisted or so (although I don't see them in the code).

Shell builtins can't be supported with stderred because builtins are contained within the shell itself, they are not executed or run. Due to this LD_PRELOAD is ignored entirely. It can't be fixed without completely changing the design of stderred. Instead you will have to use a shell plugin (e.g. a zsh plugin) for that.
