    And given it provides 256 colors in Screen, the entry should
probably be named yet longer "screen-256color.xterm-256color"... :-)

    Each and every official 256 colors terminfo entry has "pairs#32767".
Namely xterm-, rxvt-, putty-, and gnome-256color. Does it really bug?

    Unfortunately customizing color palette doesn't work: This escape
sequence is filtred by Screen and never reaches Xterm. "tput initc 4
1000 200 600" doesn't change blue to rose. You should either remove
ccc/initc, or find a way to open a hole in Screen's barrier.

    For screen.putty entry I've just done the later, enclosing the
needed sequence in between \EP and \E\\, and it works like a charm. But
for Xterm there is a problem with \E\\: I don't know how to send ESC \
to the underlying terminal, or if \007 would do it.

Bye!    Alain.
