Use character-parser for js-expression parsing
Escape JavaScript strings as late as possible

improve the hygiene of compiled functions

the variables I have namespaced are:
+ __indent -> jade.indent
+ [escape, merge, attrs, rethrow] -> straight namespace
+ interp -> jade.interp
+ __val__ -> jade.interp
+ __jade -> jade.debug
