Screens that don't have a black border around the active area will have
ugly black bars for the margin when the text background color is not black.
This is especially noticeable on an LCD screen (not the backlit kind) when
the terminal colors are inverted.

Also when you have multiple monitors of different resolutions (VT does
mirror them which is quite pointless, but hey, VT is meant for rescue tasks
so for fancy features you'd better use X).

I see this on nouveau which your patch doesn't handle, but we can extend it
to nouveau later.

Ah. I see what you mean now. The margin will be whatever is set for the
vc_video_erase_char in the kernel, which can be changed by userspace. I
tried midnight commander and sure enough, I still have the black margins
when I invert the screen (`setterm -inverse on`). Interestingly, after
allowing the console to blank after a timeout, the console was blanked with
white, then after pressing a key to unblank, the margins were also white.

"setterm -inverse on" looks ugly.

I've just added reverse to my vtgamma (https://github.com/kilobyte/vtgamma),
it uses a different method (setting the palette instead of \e[?5h) which on
VT looks a lot nicer.
