Function: This is used by WRITE-STRING. It writes the string to the stream, optionally delimited by start and end, which default to 0 and NIL. The string argument is returned. The default method provided by FUNDAMENTAL-CHARACTER-OUTPUT-STREAM uses repeated calls to STREAM-WRITE-CHAR.
Function: Write STRING to PATHNAME. The EXTERNAL-FORMAT parameter will be passed directly to WITH-OPEN-FILE unless it's NIL, which means the system default.
