I was expecting terminal emulators like rxvt-unicode to have a default
color pair, but I thought tmux did not have any, and was simply re-using
the default from the terminal in the client.

I don't really understand from where this 7 comes, unless it's some kind
of default color pair internal to tmux, but then how can such a value be
set?

As I said in my previous e-mail, there are two ncurses with two
different databases, and it messes things up. For example
`tput setaf 7 | cat -v` outputs "^[[23m", but that's because tput is
using the terminfo database from port ncurses, while tmux uses
(probably) termcap database from base ncurses, which contains
:AF=\E[38;5;%dm:
Here are the relevant termcap entries (I hope it's not too spamy):

The last entry is from my $HOME/.termcap, while the rest comes from
system /usr/share/misc/termcap (symlinked as /etc/termcap). Because the
changes to $HOME/.termcap were reflected immediately, I think there is
no compilation needed.
The main reason for using the last entry was that in port ncurses
database, rxvt-256color refers to 256 color version of rxvt (it makes
sense) and not of rxvt-unicode. So at first it was only an alias, and
when I was tmux FAQ about reverse-video versus italics with
rxvt-unicode, I added so/se and ZH/ZR capabilities.
Now if you're asking for `infocmp` output, I guess you're more familiar
with terminfo format than termcap, so I will try to merge the above
entries and convert them. Since I'm not completely certain I'm doing it
right, and whether port ncurses tool interprets termcap exactly like
base ncurses libraries, you should probably consider the above termcap
much more reliable than the below terminfo.

By the way, I'm surprised by the number of differences between this and
the (irrelevant for now) terminfo entry in ported ncurses. However I
have no idea how to test which one is the most accurate.
Thanks for your help,
