Current version vi is not 8-bit clean.
Attached patch:
a) correcting show locale depend printable and unprintable as '.' chars.
b) show 127 char as '^?'
c) parse 149-255 keys code as symbols (128-148 used by algorithm)
d) more size optimization - 300 bytes
e) added console 'Home' and 'End' keys
f) remove one bug - strlen(NULL)
g) more fast screen output - use buffering stdout
h) better parser input escape sequiences

and small "i18n" patch to libbb/procps.c
