Wrong heredoc kills Docker LS

[danCrespo]

Type: Performance Issue

Steps to reproduce.

• You can start writing a Dockerfile
• Use a RUN instruction (not sure if the issue also happens with any other instruction)
• Start the command using a here-string <<<CRASH , as if it were a heredoc. (I already know this sintax is wrong and invalid)
• Enter a new line and type anything...
• Close the wrong heredoc CRASH and...
  that's when the LS is killed by this wrong sintax.

Thanks for the bug report, @danCrespo. I was able to reproduce the problem and have opened rcjsuen/dockerfile-ast#117 to track this.

You're welcome @rcjsuen. Please let me know if you need any other resources: a screenshot, more details, or anything else that can help you. Although I think the mistake speaks for itself, I'm happy to help further. Greetings
