Interesting. Because "archive" has to incur a large I/O cost anyway, I expected extra allocation for correctness for only the directory paths would be dwarfed in the noise.

I actually care more about cases other than "archive", though. Do we even feed directory paths to the machinery?

Yes, what we do with wildmatch is a separate issue for 'master' and upwards.
