[PATCH v4 22/24] t1600: add index v5 specific tests

[Thomas Gummerer <t.gummerer@gmail.com>]

Add a test that tests only index v5 specific corner cases, to protect
against breaking them in the future.

Currently there is only one known case where the sorting is broken if
the index is read filtered with two different length pathspecs.
