Gee whiz! Just when I thought I had the "period within quotation marks" rules set firmly in my personal punctuational code, I hit upon this sentence:
All message IDs are pre-pended with the value “ID:”.
As a reviewer, should I advise my author to stuff that very American period inside the quotation mark? Wouldn't that not only look rather ugly but also somewhat confuse the fact that the item within the quotation marks is to be typed verbatim by the reader? What would be community-advised in this case?
