You're making a mistake of catering to Unix shells which are pure garbage
as programming languages instead of fixing them or switching to saner
alternatives and then "fixing" kernel to sort-of workaround Unix shells
deficiencies.

Formally, you patch will break every program which creates git-style files
with filenames only fixing up for \0 and '/'. Now such program should
account for low ASCII as well.
