colors in vi don't work in X

[pertusus at free.fr]

Hi,

When I open vi in X with a simple file needing color (in that case a texi 
file) the escape sequences for color  are written as is instead of coloring 
the output. On a tty it works fine.

Here is what it looks like in vi (in xterm, konsole, gnome-terminal):

^[33m\input texinfo.tex    ^[34m at c -*-texinfo-*-
                                                                                
text
                                                                                
^[33m at bye
^[34m~
