The one value per file rule comes in part from files such as this
stat file.  We've been learning the hard way that complex ascii file
formats tend to be a pain to parse, and a pain to evolve.  So we're
trying to do better in future files.  Greg K-H has been especially
clear on the need to do this in /sys files.  We can't change the format
of old files very well, but we can do better with new files we add.
The one most common exception to this rule that I find persuasive is
for a vector of values of the same type and semantics.
