BTW, the compiler already emitted a warning for it, but saying only
that there was a call to an unknown function `,`, and without specifying
where that call was found.

So now we get a duplicate warning:

    In my-foo:
    foo.el:4:7: Warning: ‘,’ called -- perhaps used not within backquote
    
    In end of data:
    foo.el: Warning: the function ‘,’ is not known to be defined.

Maybe the better fix is to improve the "function ‘,’ is not known to
be defined" warning so it points to the right location?
