sqlfmt keeps adding \tab before every line wrapped with triple quotes.

Reproduce steps.
One can define a macro, say, to select columns depending on key:

{% macro test(key) %}
   {% set columns_by_source = {
      "a": """
          column_a1,
          column_a2,
          column_a3,
      """,
      "b": """
          column_b1,
          column_b2,
      """,
    } %}
   ....
{% endmacro %}

Now every time, running sqlfmt -k -l 80 ., sqlfmt will add \tab before each line continuously moving rows right.
Locally you can skip -k flag, but then if you have .pre-commit hooks in GitHub, it might prevent from merging as sqlfmt check will always fail.

What is the output of sqlfmt --version?
