That is equivalent to say
if (git_env_bool(GIT_TEST_COMMIT_GRAPH, 0))
revs->limited = 0;
Wouldn't that make the codepath that involves limit_list()
completely unreachable while testing, though?
The title only mentions "topo-order" logic, but the topo-order is
not the only reason why limited bit can be set, is it? When showing
merges, simplifying merges, or post-processing to show ancestry
path, or showing a bottom-limited revision range, the limited bit is
automatically set because all of these depend on first calling
limit_list() and then postprocessing its result. Doesn't it hurt
these cases to unconditionally drop limited bit?
