I can confirm that this fixes the local dir case in the simple test I
posted previously (and the remote dir case was fixed by the process-file
fix previously).

I don't get that failure with the current code, so maybe it has been fixed already (?):

,----

`----

Not sure why I have a different number of tests/expected failures either.

But in any case, the main problem is resolved.

Thanks for the fixes!
