 I love new media! Anyway, the default columns value is 3, so here's a
 scenario:

 1. Add a new post
 1. Hit Add Media, Create Gallery, select a few images and hit insert.
 Switch to Text mode. You'll see the gallery shortcode has been inserted
 with only the `ids` attribute, which is expected.
 1. Make sure you're in Visual mode. Select the Gallery and hit the little
 Edit Gallery button, set Columns to 5, hit Update Gallery and switch to
 Text mode. You'll see that the gallery shortcode now also has
 `columns="5"` which is expected.
 1. Edit the gallery again and set Columns back to 3. Hit Update and switch
 to Text. You'll see the shortcode has `columns="3"` but expected to see no
 `columns` attribute since 3 is the default.

 The same behavior happens on the `link` attribute. The "correct" behavior
 happens on the `orderby="rand"` attribute, which is removed from the
 shortcode when set to the default (off) state.
