I myself didn't even know the behaviour for ../../version/whatnot...
I must dive into the sources to fix this oversight in the docs.

Probably you hit the nail on the head there :)

a) There are so many ways to do it
b) There are so many platforms.
I prefer to document the possibilities and let the user figure out for himself what works best.
I do think we can certainly make the default behaviour more 'version aware' by installing
a config file that already implements one of the different schemes.
That said, I am still not convinced of the need for this, I work since many years with
a single pretty standard config file, which I've never had to edit.
