Why not tmux-256color?

[xu-minghao317]

Now it is

# Upgrade $TERM
set -g default-terminal "screen-256color"

but why not

# Upgrade $TERM
set -g default-terminal "tmux-256color"

tmux color term enables italic font and ensure more color consistency with xterm-256color which is usually the case outside tmux.

Your suggestion is certainly sensible because it is supported by the tmux wiki: https://github.com/tmux/tmux/wiki/FAQ#i-dont-see-italics-or-italics-and-reverse-are-the-wrong-way-round, and by my experience.

When used in conjunction with fzf the current setup results in a common fzf issue: junegunn/fzf.vim#1356 (comment)

Using set -g default-terminal "tmux-256color" instead resolves this. Might be worth to changes this.
