And be aware that some editors hate ellipses with a fiery passion and will remove every single one. Aim to not use more than a handful in a novel and maybe they'll let some remain.
Maryn, not a big user of ellipses, but guilty on dashes
I wouldn't allow an editor to remove ellipses. This is the writer's decision, not the editor's. Editors should not "let" anything like this stay or go. Writers are the ones who decide to let them stay or go.
But I've never met an editor who hated ellipses. Never. I've never had an editor remove an ellipses, or even bring up the subject. They're a very common way of indicating a pause, and have been for many decades. You can overdo anything, including ellipses, but my experience is that it's overuse an editor might dislike, whatever the overuse is, not the use itself.
Writers really need to understand more about the editing process after a book sells. The writer is in charge, or should be, not the editor. The editor makes suggestions, and the writer can take them or leave them. This includes such things as ellipses. When an editor tries to eliminate something like this, he's screwing with the writer's style, and no good editor does this.
