Re: [PATCH v7 04/10] t6099, t6600: add side-exhaustion regression tests

> From: Kristofer Karlsson <krka@spotify.com>

> Add t6099 to test the case where multiple merge-base candidates exist
> and one is an ancestor of another. This exercises the side-exhaustion
> optimization in paint_down_to_common together with the
> remove_redundant safety net in get_merge_bases_many_0.

> Add a mixed finite/INFINITY test to t6600 where one tip is outside
> the commit-graph (INFINITY generation) and the other is inside.
> This exercises the region transition: the walk starts in the
> INFINITY region where side-exhaustion is disabled, then crosses
> into the finite region where it can fire.
