 @brief abstract input adapter interface
 
 Produces a stream of std::char_traits<char>::int_type characters from a
-std::istream, a buffer, or some other input type.  Accepts the return of
+std::istream, a buffer, or some other input type. Accepts the return of
 exactly one non-EOF character for future input. The int_type characters
 returned consist of all valid char values as positive values (typically
 unsigned char), plus an EOF value outside that range, specified by the value
