- return cstring_to_text("");
+ return cstring_to_text_with_len("", 0);
This looks worse, so we'd better be getting something in return.
I agree this is a bit ugly. I wonder if we'd be better off creating a
function that returned an empty text value, so we'd just avoid
converting the empty cstring altogether and say:
return empty_text();
