Why are you insisting on everything being explicitly mentioned. I
agree there are areas in the document that could do with
improvement, but adding "for" alongside "if" and "while" isn't one
of them imo.

Yes, there are counterexamples, but largely due to the mixture of
Xen and Linux style files (and sometimes within a file). This is
unfortunate, but there are sufficiently many good examples in
case you can't derive the general rules from the examples given

But I don't think you'll find many bad examples throughout xen/ for
this one.

As said above - useful improvements to the document are welcome,
but adding stuff that is intentional to be implied doesn't fall in this
category afaic. The document should remain reasonably short, or
else we risk people not reading enough of it.
