Thank you! It will be included in 'pu' as gc/gen-format-status-improvements.

I have squashed the commits and reformatted/reworded the commit comment
according to our standards.

Sorry I missed this one when it was posted. It was on the wrong

Sorry about that. Instead I did some more work on the commit formatting.
