+** new procedure: ftruncate PORT [LENGTH]
+Truncates PORT after LENGTH bytes, or at the current position if

+The arguments are the same as for the old fseek procedure, but it

+** the fseek procedure now works on string ports, since it has been
+redefined using lseek.

+** the setvbuf procedure now uses a default size if mode is _IOFBF and
+size is not supplied.

+** the newline procedure no longer flushes the port if it's not

+Drains PORT's read buffers (including any pushed-back characters)
