Thanks - pushed.

I see what happened here:

(1) The upstream fuse_opt_add_opt_escaped function returns int.
However I rewrote this copy of the function so much that it no longer
returned anything.

(2) Because the function is not needed if you have recent fuse, we
weren't testing this so there were no gcc warnings.
