I find another detail interesting in this generated patch.
The Coccinelle software suggests here to delete also a blank line
at a specific source code place. I would usually interpret
this SmPL script example in the way that I did not express the removal
of blank lines.

How often do you care if additional source code reformatting should
happen around a specific change (or not)?
