libnm/docs: Preserve newlines in generate-docs-nm-settings-docs-gir.py
Previously it was hard to read long paragraphs.
Issue: #956 (closed)
New output sample: https://gist.github.com/igo95862/deb5957ce5672ae7f646f28cf82fe1d7 (notice the paragraphs, these are native new lines)
It is also possible to use Python's textwrap
to have paragraphs that are not based on source code.
