Agreed. I added a sentence in the first mention of GET DIAGNOSTICS, and indicated it was generic for that command. What I also added was your description of when to use := and =, but I put it in the C comments so we have a record of it and if we need to expand the description or behavior later.
I'll be more happy if a comment about GET DIAGNOSTICS statement will be in user space.
