So, fold-port-matches reads the port one character at a time, IIUC (I
don't really understand it).

I think we don't need to do that in this case. We could instead do
Boyer-Moore and skip 34 bytes + the length of %store-directory, which
could speed things up a lot.

But, I don't think we should wait for that in order to push this patch
:)
