.tmux.conf, might use it instead of screen

Initial version from:
https://github.com/sdt/.dotfiles/blob/master/tmux.conf
tmux bash completion

from the tmux examples
disable xon/xoff w/ stty for interactive shells

Just putting the stty stuff in .bash_profile didn't fix
non-login bashes under screen or tmux.
Can't assume terminal, although I think checking $PS1
in .bashrc would be enough..?
Use Control-s under tmux to switch terminals
tmux status off globally
tmux .tmux.conf comment
note command used for 2 new windows
alternate-screen off, I like the mess
kill unattached sessions for reference
.Xresources italics in URxvt.colorIT: red
use to screen-like italics highlight for /search

If .terminfo/s/screen-256color-noit exists then use it
to replace the italics with highlighting.  (tmux 1.5)

mkdir -p $HOME/.terminfo/
infocmp screen-256color | sed \
 -e 's/^screen[^|]*|[^,]*,/screen-256color-noit|screen with bold for italics,/'\
 -e 's/smso=[^,]*,/smso=\\E[7m,/' -e 's/rmso=[^,]*,/rmso=\\E[27m,/' \
 -e '$s/$/ sitm=\\E[3m, ritm=\\E[23m,/' > /tmp/terminfo

tic /tmp/terminfo # compiles to .terminfo/s/screen-256color-noit
infocmp screen-256color-noit &>/dev/null ; echo $?

(This is mostly cut and paste voodoo)
