older version (without mustache standalone tag handling):

template: 1\n{{foo~}} \n\n 23\n{{bar}}4
output: 1\n23\n4 ( all space and line change are removed after {{foo~}} before 23 )

current version (with mustache standalone tag handling):
http://builds.handlebarsjs.com.s3.amazonaws.com/handlebars-cf343a1.js
http://jsfiddle.net/4Lkmnru6/1/
template: 1\n{{foo~}} \n\n 23\n{{bar}}4
output: 1\n\n 23\n4 (only one space and line change are removed after {{foo~}} before 23 )

Questions:

1. should space control behavior work just like old version?
2. space control should be handled before or after standalone tag detection?
