24 bit color in emacs, under Blink.sh
What's the problem?
The normal way to enable 24 bit color on a recent emacs (27.1) and a recent OS distribution (one which already has the terminal type definition
xterm-direct), is just to set
TERM=xterm-direct before running emacs.
But this does not work with blink.sh, probably because of some incompatibility in its underlying library, hterm.
