escape sequences which begin with `%'. When specifying a format
string, the usual C backslash characters are honored: `\\b', `\\f',
`\\n', `\\r', and `\\t'. Continuation lines in format files end with
-`\\' followed by the newline character.
+`\\' followed by the newline character. A literal `%' can be inserted into
+a format file by using the sequence `%%'.
