[PATCH 1/4] t7006: document that `pager.foo` can be partially preserved

["Martin Ågren" <martin.agren@gmail.com>]

Assuming a blank slate, consider the following configuration:

[pager]
	foo = some-command
	foo = false

Now `git -c pager.foo=true foo` will page using `some-command`. This
might have been intended, or is perhaps just a side-effect of the
implementation. In any case, it could be useful and someone might rely
on it, either knowingly (as above) or not (if these lines are spread out
across the configuration).

However, `git --paginate foo` will *not* use `some-command`. That
matches the documentation (Documentation/git.txt).

Upcoming commits will expand on how paging for `git foo` can be
configured. Those commits mustn't change how `pager.foo` behaves, so add
tests for these two cases.
