`ag --nofilename` leaves newlines between output for individual files

[Dan Watkins]

Steps to reproduce:

In a pristine directory:

$ echo foo > a
$ echo foo > b
$ ag foo # This is as expected
a
1:foo

b
1:foo
$ ag --nofilename foo # But not this
foo

foo

Actual behaviour:

"foo\n\nfoo"

Expected behaviour:

"foo\nfoo"

(This is particularly annoying when trying to use ag's output programmatically, because you have to ignore/skip the newlines.)
