This really should be merged. The contributor has maintained the intention of the original code -- which was to include in `toString` only if set -- and has fixed some obvious bugs.
I agree with your `[minor]` suggestion that the intention of the original code was less than ideal but I think it's poor form to decline or delay a PR such as this on the basis that we would like to see yet further improvements to the original code. --- Reply to this email directly or view it on GitHub: https://github.com/jclouds/jclouds/pull/907#issuecomment-193721237
