Hmm OK. That is a general property of /proc and /sys files that are
dynamically generated, so users probably need to get used to it :)

But OK. That sounds sane enough. My only worry is that it might confuse
some tools, ie. the file claims to be x bytes but is actually smaller.
But I guess that can actually happen anyway with any file.

So I'll merge this and stop blabbing :)
