[racket-users] telling apart files ending with a newline

Suppose I have two files that are identical, except one ends in a newline and the other does not. If I use `read-line` to read the successive lines of this file, because it swallows the line separators, there is no way to tell them apart. E.g., these two strings "a b" and "a b " read using `
