then it will not handle most of our cases :-/ Actually if it's in the form:
const char *s = eina_stringshare_add(bla);
size_t len = eina_stringshare_strlen(s);
it's better (minimal performance gains) to write it like:
size_t len = strlen(bla); // if you know it's !NULL
const char *s = eina_stringshare_add_length(bla, len);
as internally eina_stringshare_add_length() will be called by
eina_stringshare_add(), and strlen() is often optimized by the
compiler if possible (ie: instead of bla you have "string" it turns it
into sizeof("string")-1).

typos :-D that's why we should not write programs in MS word kids! ;-)
