[PATCH 2/4] docs/config: give a relative includeIf example

[Jeff King <peff@peff.net>]

The changes in the previous commit hopefully clarify that
the evaluation of an include "path" variable is the same no
matter if it's in a conditional section or not. But since
this question came up on the list, let's add an example that
makes it obvious.
