    scalar: fix wrong shell hashbang
    
    The bin-wrappers/scalar seems like missing setting $SHELL_PATH_SQ which
    lead to I can't execute bin-wrappers/scalar correctly, which output
    error:
    
    zsh: exec format error: scalar
    
    (this bug will not turn out in bash)
    
    The bin-wrappers/scalar begin with wrong hashbang "#!", which cannot
    figure out by zsh. So this patch want to fix this problem.
    
    v1: Setting $SHELL_PATH and $SHELL_PATH_SQ in scalar/Makefile.

Thanks for finding this! However, while your patch fixes the error you've
identified (I was able to recreate both the original issue and apply your
patch to fix it), I believe it has already been fixed in 'next' by
7b5c93c6c6 (scalar: include in standard Git build & installation,
2022-09-02) (archive: [1]).
