I guess he means that he doesn't like functions which are only called
from one place - he'd rather like to see the code directly at the
callers site.

However I do not agree here - functions have also a documentation
effect, so I vote to keep the function.  If neccessary, we could declare
the function inline, but this is really overkill here.

Yep.
