[7m single-command [0;0m

The %%% prefix Starts a Single Command Over Multiple Lines (?)

This special lexer mode has several use cases:

Long command lines without trailing \

    %%% chromium-browser
        --no-proxy-server
        # comments allowed
        --incognito

Long pipelines or and-or chains without trailing \ 

    %%% find .
        # exclude tests
      | grep -v '_test.py'
      | xargs wc -l
      | sort -n

    %%% ls /
     && ls /bin
     && ls /lib
     || error "oops"
