** the procedures uniform-array-read! and uniform-array-write! now
work on any kind of port, not just ports which are open on a file.
** now 'l' in a port mode requests line buffering.
** new procedure: ftruncate PORT [LENGTH]
Truncates PORT after LENGTH bytes, or at the current position if
LENGTH is omitted. Works on random-access file and string ports.
** new procedure: lseek PORT/FDES OFFSET WHENCE
The arguments are the same as for the old fseek procedure, but it
works on string ports as well as random-access file ports.
** 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
line-buffered: previously it did if it was the current output port.
** open-pipe and close-pipe are no longer primitive procedures, but
an emulation can be obtained using `(use-modules (ice-9 popen))'.
** the freopen procedure has been removed.
** new procedure: drain-input PORT
Drains PORT's read buffers (including any pushed-back characters)
and returns the contents as a single string.
