St Emacs 256 colors

Emacs starts very slowly in st with default settings.

Put this in your init.el:

(defvar xterm-extra-capabilities nil)
(defvar xterm-query-timeout nil)

(add-to-list 'term-file-aliases
             '("st-256color" . "xterm-256color"))

Details in /usr/share/emacs/27.1/lisp/term/xterm.el
