+When using the #(command) construction to include the output from a command in

+could be used:
set -g status-right "#(echo \\\\(test\\\\))"
set -g status-right '#(echo \\\(test\\\))'
-With the double-quotes, the string when is first parsed will be set to
-#(echo \\(test\\)), and then again parsed as echo \(test\) before passing the

+In both cases, the status-right option will be set to the string "#(echo
