Improper lists in list_to_binary/1

I see that our documentation is slightly incomplete.
Several BIFs accept what we call I/O lists. I/O lists are
mentioned but not completely defined in the documentation for
port_command/2 (in the erlang man page). I/O lists have been
supported for a long time (maybe even in OTP R1B).
An I/O list is a deep list of binaries and integers in the range
0 through 255 and binaries. Furthermore, a binary is allowed
in the tail position of a cons cell. (An integer is NOT allowed
in the tail position.)
Some of the BIFs that accept I/O lists are:
We will clarify the documentation in a future release.
