Ah, this is a very useful thing.  Suppose you have something like:

struct thatthing stuff[] = {
    { "squid",   145,  5.2,    "fish" },
    { "parsley", 130,  2.5,    "vegetable" },
    { "flaps",   556,  2.1,    "human" },
    { "C",        11,  0.598,  "programming language" },
};

It is _much_ easier to edit a list like this if every line has the same
format, including the trailing comma.  It is also somewhat easier to
generate automatically.

Yes.
