This highlights `RUN`, `CMD`, and `ENTRYPOINT` lines using shell highlighting. It doesn't bother detecting the JSON forms, but that's OK because JSON arrays highlight pretty reasonably with shell highlights. :) Signed-off-by: Andrew "Tianon" Page <admwiggin@gmail.com> Upstream-commit: 62d3b1bf2e830b6cdf7c4df86d356d48b58b1ab0 Component: engine

" 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)
