Sure, that's fine as advice.  Fwiw, it's different for different distros.

Declarations that using posix-compliant continuations is "highly unusual abuse 
of POSIX shell semantics" is a different matter.

Changing/breaking behavior in managing valid/working grub configs, and 
rationalizing it by "I do not see a need to support it"

 is ... unhelpful.

Particularly if Grub project/devs say that its usage *is* OK & compliant.  
Which is why I asked _here_; and, iiuc, seems that it *is*.

Grub's stability, reproducibility and portability are critical.  It all works 
great, particularly when the excellent docs are followed.

Happy to take ongoing conversation to the bug.
