Whitespace cleanup (miekg#10)

* Whitespace cleanup

My commit c0c307b used spaces instead
of tabs, which makes any view that has a tabsize other than 4 pretty
awful. My apologies.

Found one separate function where spaces were used as well and changed
that one as well (though the problem is not as bad there)

* gofmt fix

gofmt fount 4 more lines to format
