Copying macro code copies the full contents of the sql file, including other macros

[dave-connors-3]

Describe the bug

in macros/foo_and_bar.sql

{% macro foo() %}
{% endmacro %}

{% macro bar() %}
{% endmacro %}

if you select a model that uses bar, both macros are copied over since we don't parse the SQL
