Reports missing continuation characters in RUN command.

In the shell form of RUN command you should use a '\' (backslash) to continue a single RUN instruction onto the next line. Otherwise, Docker build will fail.

Examples:


  # the command below will fail
  RUN /bin/bash -c 'source $HOME/.bashrc;
      echo $HOME'

After the quick-fix is applied:


  RUN /bin/bash -c 'source $HOME/.bashrc; \
      echo $HOME'
