Updates since v2: - Fix tab which crept into 1/4
- Fixed the benchmarking code in the commit message in 2/4 to just always load JSON::XS -- the previous version was the version where I'd broken that to force loading of JSON::PP. - Remove the --no-pretty from the t/ version of query-watchman in 2/4; I don't know how I messed up diff'ing the file previously, but if there are already differences, it makes sense to let them slide.
