Description Christian Weisgerber 2000-10-21 14:40:01 UTC 
There's a bug in our vi (nvi 1.79).  The options "noprint", "print",
and "octal" don't work properly.  When these options are changed,
the routine that evaluates them is called before the option has
been set.

Fix: From NetBSD:
How-To-Repeat: 
For option "octal":
* Insert a non-printable character >0x80.
* :set octal
  => The character is still displayed in hex.
* :set nooctal
  => The display switches to octal.

Similarly for "print" and "noprint".

Fixed without additional flags in -CURRENT.

PS: you may need LC_CTYPE=C (8-bit mode) to test this feature if the
non-printable character is not a valid Unicode character.

The best way to predict the future is to invent it.
