fix: behavior of hard line breaks in Format strings (#8457)
This PR fixes an issue when including a hard line break in a `Format`
that caused subsequent (ordinary) line breaks to be erroneously
flattened to spaces.

This issue is especially important for displaying notes and hints in
error messages, as these components could appear garbled due to improper
line-break rendering.

-- This tests the `#info_trees in` command.
-- If it proves too fragile to test the result using `#guard_msgs`,
-- it is fine to simply remove the `#guard_msgs` and expected output.
