colorize: only emit osc8 if [general].enable-osc8=true
Some old versions of less do not handle OSC 8 escape sequences. Even if aerc's embedded terminal is configured to handle them, less corrupts them making the output unreadable. 8;id=colorize-1;https://foobar.com/stuff/https://foobar.com/stuff/ When [general].enable-osc8 is set to false (its default value) do not attempt to generate OSC 8 sequences with the built-in colorize filter. These sequences would be stripped out anyway. Reported-by: Omar Polo <op@omarpolo.com> Signed-off-by: Robin Jarry <robin@jarry.cc> Acked-by: Kirill Chibisov <contact@kchibisov.com>
