First line of shell code is not highlighted

[vallentin]

Hey. Thanks for the extension, this was exactly what I needed.

However, I encountered an issue. Sometimes the first line of shell code is not highlighted correctly. I tested a few other languages, and they seem to work fine.

- bash: | # shell
    # Foo
    # Bar
    # Baz

- bash: | # shell
    echo Foo
    echo Bar
    echo Baz

However, the following case works fine.

- bash: | # shell
    if [ -e foo/bar ]; then
      echo Foo
      echo Bar
    fi
