Keep indentation for multiline statements

[gsemet]

Here an exemple of Dockerfile part the way I like to write:

RUN     true \
    &&  apt-get --quiet update --yes \
    &&  apt-get --quiet install --yes --no-install-recommends \
            curl \
            dos2unix \
            git \
            htop \
            iftop \
            iotop \
            jq \
            make \
            netcat-openbsd \
            python3-pip \
            vim \
    &&  true

I find it really efficient, merge-friendly, extendable, etc. So I want to keep it this way.

If I enable autoformatting and this extension, on save these lines are automatically rewriten to:

 echo "Acquire::https::Proxy \"http://nexus.tls.renault.fr:911\"\;" >> /etc/apt/apt.conf \

RUN     true \
    &&  apt-get --quiet update --yes \
    &&  apt-get --quiet install --yes --no-install-recommends \
    curl \
    dos2unix \
    git \
    htop \
    iftop \
    iotop \
    jq \
    make \
    netcat-openbsd \
    python3-pip \
    vim \
    &&  true

@gsemet Thank you for taking the time to open this request. I have opened rcjsuen/dockerfile-utils#62 to track this.

Have a nice day!
