Ah, ok; so it's to avoid spending time in remove_marked_cache_entries().

I think (though it wouldn't come up in your application) that to keep
this and avoid caller confusion one would need something like

		if ((cache[i]->ce_flags & CE_REMOVE) ||
		    (cache[i+1]->ce_flags & CE_REMOVE))
			continue;

in the other loop.  I say "something like" because a person could have
marked some some but not all stages with CE_REMOVE, causing
file/directory conflicts to be missed.

Thanks for the explanation.
