Ryan Boehning be4b7c1474 Update for Go 1.10 (#39)
* Add Go 1.10 to .travis.yml.
* Add quotes to Go versions in .travis.yml, because unquoted 1.10 is interpreted
as Go 1.1.
* Change .travis.yml references from 'tip' to 'master'. 'tip' is a legacy reference
coming from the days when the Go project used mercurial instead of git.

Olivier Poitrey 447d0fc7f5 Optimize JSON encoding even further
Last optimization was for JSON string with no character to encode. This
version focuses on strings with some chars to encode, trying to apply
the same trick for substrings that do not need encoding.
