I'll counter your wiki entry with another:

The Chicago Manual of Style suggests the use of an ellipsis for any omitted word, phrase, line, or paragraph from within a quoted passage. There are two commonly used methods of using ellipsis: one uses three dots for any omission, while the second makes a distinction between omissions within a sentence (using three dots: . . .) and omissions between sentences (using a period and a space followed by three dots: . ...). An ellipsis at the end of a sentence with no sentence following should be followed by a period (for a total of four dots).
