>Description:
editors/fileobj is a vi for binaries.

When starting it up on a new file (e.g., "fileobj /bin/ls"), it
starts in file position zero and only that cell is colored (black
on green). When moving around, cells that are entered are coloured
blue, lightgrey, or green depending on their value.

I understand that the color should be there from the beginning. tkusumi,
please correct me if I'm wrong.

It also comes with a test mode:
fileobj --test_screen
This prints, among others:

â??This should look reversed.
|This may or may not look reversed.
|This should be in black,green.

All of these lines are just white-on-black (i.e. reversed) when I start this on an xterm
or in tmux configured with screen-256color.

I'll attach a screenshot later.
So the "black,green" is just black and white.
>How-To-Repeat:
See above.
>Fix:
Yes, please.
