When specifying format attribute for functions where the intended argument must
be of literal string, if said string is passed off to another function that
requires said argument to be of a string-literal, warnings will occur.
Interestingly standard-library marked functions can be wrapped and no warnings
will occur, this seems to only manifest with user-defined wrappers around other
attribute format wrappers. Included is an attachment showing the problem as
described and various methods of trying to get around it, annotated of course.</pre>
