Loose parser incorrect parsing with incoherent indentation

[pantoninho]

Acorn's loose parser incorrectly parses code if the indentation is not coherent.
This problem does not occur with the main parser.

Sorry for the brief report, will update with more details soon (if needed).

sample test:

const acorn = require('acorn');
const { parse_dammit } = require('acorn/dist/acorn_loose');
const escodegen = require('escodegen');

const code = `
{
        console.log('should be inside block');
    console.log('should be inside block');
}
console.log('should be outside block');
`;

console.log('\n----------- ACORN PARSER -----------');
console.log(escodegen.generate(acorn.parse(code)));
console.log('\n-------- ACORN LOOSE PARSER --------');
console.log(escodegen.generate(parse_dammit(code)));

loose parser output:

{
    console.log('should be inside block');
}
console.log('should be inside block');
console.log('should be outside block');

That is by design. See #199 for more discussion.
