`\?` is undefined for POSIX BRE, from:
https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html#tag_09_03_02

> The interpretation of an ordinary character preceded
> by an unescaped <backslash> ( '\\' ) is undefined, except for:
> - The characters ')', '(', '{', and '}'
> - The digits 1 to 9 inclusive
> - A character inside a bracket expression

This test is failing with busybox grep.

Fix it by using character class.
