== Removal of Section Headings == 

 This article had two minor headings of "Usage in Typography" and "Usage in Computing," each containing one or two sentences. Such brief lists of disconnected sentences do not warrant a new section, and makes the article look choppy and divided. After reading the article, it appeared that they can be blended into the original "History" section, since these are simply the contemporary 'history' of the phrase. The name "History" was changed to "Overview" to better reflect both past and current usage. Thus, the article now reads as one coherent prose. All references were kept.
