range is incorrect

[ariovistus]

I have some code here: https://github.com/ariovistus/esprima-bug

test.js uses esprima 4.0.1 to parse tok.js and outputs

define "urijs" 2250,2265

which is the position of the last part of tok.js, define("urijs"), as reported by esprima. but it is wrong, the actual position should be 2272
