A pet sidetrack project. :-)

I'm still learning the subtleties but the console clearly can do bright
text on a bright background that the emulators don't.

The color scheme for Xterm is quite useable to me with these "correct"
colors.

I'll attach a shot of URxvt where I started Tlf as:
TERM=xterm-256color tlf
it is not much different, if at all.
What I see of the UI code in Tlf is that rxvt is handled such that it
tries to play the part of the Linux console.

I did get private feedback from a user that prefers the console so I
think it should be left well enough alone.
As for Xterm and URxvt, I think if Tlf just treats them the same as far
as colors are concerned and recommend using our Xresources, then I think
we'll have a good level of consistency. Actually, I am unsure of people
choosing URxvt instead of Xterm these days but some may. Plus, this has
become a bit of an interesting subproject of mine.

Ah, that is the secret. I think I was puzzled why I couldn't get that
keyword to work last winter.
The reason I am promoting Xterm is due to it not consuming the key
combinations that other terminals consume. Keys like F11 and
Ctl-PgUp/PgDn come to mind. Xterm also supports anti-aliasing with
TrueType fonts these days so it can look quite nice on the modern desktop
(I'm using Gnome these days).
