tests: local config file should be honored from subdirs of toplevel

When git is passed the --paginate option, starting up a pager requires
deciding what pager to start, which requires access to the core.pager
configuration.  If --paginate is handled before searching for the
git dir, this configuration will be missed.

In other words, with --paginate and only with --paginate, any
repository-local core.pager setting is being ignored [*].

[*] unless the git directory is ./.git or GIT_DIR or GIT_CONFIG was
set explicitly.

Add a test to demonstrate this counterintuitive behavior.  Noticed
while reading over a patch by Duy that fixes it.
