I strongly agree.
As someone said, this only applies to relatively few help pages,
and I'm not sure if it's worth (at the moment) of first
designing a rendering scheme to emphasize your current platform.
Maybe even to the contrary, I'd want the PDF version of the
help page to (almost (*)) entirely platform independent.
It depends how thing *are* platform dependent.
If one function argument only applies to Windows, then the
corresponding paragraph could simply start,
"On Windows, .....".
In other situations, using something similar to what Henrik
proposed, a \section{..} on platform specific parts would
suffice.
I also find it very important that I read on "my" (OS) help page,
about less or more functionality on another platform, and I'd
rather want the full details of that platform than just
a note that something is platform dependent.
Of course, there's the situation of missing / extra capabilities()
but I think these are well documented where applicable, and they
*do* follow the idea that you should also learn about things
that are currently not available to you.
