Indeed, I clearly overlooked option -t (transactions) which I never use.

Tested. There is a small issue because the \n is missing.
Here is another version which just replaces duration by time_include,
as they should be pretty close, and fixes the style so that it is the same
whether the detailed stats are collected or not, as you pointed out.

Indeed. The documentation is manually edited when submitting changes so as
to minimize diffs, but then it does not correspond anymore to any actual
output, so it is easy to do it wrong.
