Instruction options are duplicated when formatting line breaks

[kirillmorozov]

Hi, I've recently discovered this cool project and wanted to integrate it into my Vim config but I've encountered a bug that prevents me from doing so.

Steps to reproduce:

cat << EOF > Dockerfile
FROM python:3.10-slim-bookworm AS development
COPY pyproject.toml /app
RUN --mount=type=bind,source=requirements.lock,target=requirements.lock \
  --mount=type=ssh \
  pip install -r requirements.lock
COPY main.py /app
ENTRYPOINT ["python", "main.py"]
EOF

dockerfmt Dockerfile

Output:

FROM python:3.10-slim-bookworm AS development
COPY pyproject.toml /app
RUN --mount=type=bind,source=requirements.lock,target=requirements.lock --mount=type=ssh --mount=type=ssh pip install -r requirements.lock
COPY main.py /app
ENTRYPOINT ["python", "main.py"]

Notice how --mount=type=ssh option got duplicated when line breaks were eliminated.

I'm using dockerfmt version 0.3.9.
