I found out why this happens, I just don't know why it only occurs since
2015-07-20.

The reason is the script is using an expression along the lines of

  find ... | tar -T - --no-recursion -cjf ...

It turns out that the --no-recursion option only works for me, if it
comes *prior* to the expression specifying the filenames to archive.
That is, I had to change the script to use

  find ... | tar --no-recursion -T - -cjf ...

instead.  Funny enough, `info tar' still contains an example using
the original order...


Thanks,
Corinna
