I think the original doc is wrong. This should be ZSTR_INIT_LITERAL. Is it?

I write the entire arguments out, since other functions in the doc has an even longer list of arguments

|
||
| - - ``ZSTR_EMPTY_ALLOC()`` | ||
| - Gets an immutable, empty string. This does not allocate memory. |

Return would be better in case of Get in functions
