ShrinkSafe obfuscates _ character when it shouldn't

[dante]

Seems like an edge case, but ShrinkSafe? is improperly replacing a single-character parameter in a function signature with a longer variable. eg:

var foo = function(_, longer){ }

turns into:

var _1 = function(_2, _3){ }

fwiw, passed same sample through YUI Compressor and get:

var a=function(b,c){}

[dante]

note, this only applies to the character "_" for some reason.

var foo = function(a, longer){}

becomes

var _1 = function(a, _2){}

[dante]

unit test failing to meet expectations.

I think closure will be the compressor of choice going forwards, and we don't have anyone working on shrinksafe, so closing this ticket.
