Your first bullet point. You must have added the check to the path line
before you added the same check to the condition a few lines above, making
this check no longer necessary.
if (!stages[i] || stages[i] == o->df_conflict_entry)
any_anc_missing = 1;
else {
If we get here, stages[i] != o->df_conflict_entry...
if (!path && stages[i] != o->df_conflict_entry)
path = stages[i]->name;
no_anc_exists = 0;
}
So you don't need the second check if you've got the first one, and the
first one makes more sense anyway; for the purposes of this entire
section, we want df_conflict_entry to count as missing, and we don't look
at the paths of missing entries regardless of whether they're specially
marked.
