Hi Ole,

as you can see I'm walking through the remaining bugs in the Debian BTS.
I tried to reproduce the issue below and need to admit that I get a
slightly different result with the currently packaged version 20210822
(I just realised that there is even 20211122 which I will upload soon).
I get a file test-parallel/out1 which is a copy of foobarbaz.

I admit I'm not comfortable with parallel (just took over maintenance
since nobody else volunteered) and may be that's simply a
misunderstanding of the docs.  It would be great if you could clarify
this.

Kind regards

      Andreas.
