Colors on TTY (v26) |

Trial and error shown that emacs holds special knowledge on terminal names:
f.ex. "xterm-something" works as 256 colors and "xterm2" works as 16
colors. This is in fact very strange because there are terminals like
"screen.xterm-256color".
So it's not good to hold special magic about term names for that. Why it
doesn't check terminfo db for that (though it checks for 24bit as doc
states)? Looks like a bug to me.
To test it:
1. infocmp your current term into file;
2. rename file and rename term inside it;
3. tic renamed file;
4. set TERM to renamed term.
And voila: it's either 256 or 16 colors depending on term name!
Another bug:
(list-color-display)
always shows 16 colors from .emacs file (or from -f option). It detects 256
colors somehow later and then list-colors-display executed interactively
shows different result.
