    syntax region shLine matchgroup=dockerfileKeyword start=/\v^\s*(RUN|CMD|ENTRYPOINT)\s/ end=/\v$/ contains=@SH
    " since @SH will handle "\" as part of the same line automatically, this "just works" for line continuation too, but with the caveat that it will highlight "RUN echo '" followed by a newline as if it were a block because the "'" is shell line continuation...  not sure how to fix that just yet (TODO)
