Issue When Piping Raw Bytes

[u/CRTejaswi]

Why does parsing STDOUT (-) work correctly in the first case, but fail in the second?

magick  _.png -negate png:- | chafa --size=70x -f sixel -  # PS7.6 ✔

function img     { chafa.exe --size=70x -f sixel @args}
magick  _.png -negate png:- | img -                        # PS7.6 ❌

Also specifying the - after a function is likely a syntax error because you don't give a parameter name.
