Research direction

Start by reproducing the two Jinja macro examples from the issue and compare their rendered output. Trace the template rendering path for whitespace trimming around macro calls, then add or update coverage for the newline case. Done means the second example renders "hello: world" without the unexpected line break.

Written by the indexing model from the issue text.

Description

This code:

{%- macro test() -%}
  {%- set foo = "world" -%}{{- foo -}}
{%- endmacro -%}
hello: {{- test() -}}

generates this expected output:

hello: world

But this code:

{%- macro test() -%}
  {%- set foo = "world" -%}
  {{- foo -}}
{%- endmacro -%}
hello: {{- test() -}}

generates this unexpected output :

hello: 
  world

I thought by using {{- ... -}} it would remove any spaces and breaklines, before and after, but it does not. Is that really expected or a bug ?

Thank you
