used instead of colspec in contexts where a color is needed.
* +nop+: does nothing, but as with every other commands, arguments may be
evaluated. So nop can be used for example to execute a shell command
while being sure that it's output will not be interpreted by kak.
:%sh{ echo echo tchou } will echo tchou in kakoune, wherease
:nop %sh{ echo echo tchou } will not, but both will execute the
shell command.
