"Please split doc into foo-doc subpackage" -> why?

[Bill Nottingham]

I just recieved one of these bugs (#492446), and I'm not sure
why we'd do this for any package.

If we split the docs like this:

- it would be inconsistent per-package
-- so an admin wouldn't know whether a package had docs or not in
   the main package without manually trying to install a foo-doc
   subpackage
-- they would no longer be there by default if they're needed

Hence, why do this, when rpm already has a --nodocs flag and
macro that can be used for space savings on live images?
