Oh, right - I should have re-read your initial email before diving
into the patch. That all makes sense given your intended purpose. I
guess your goal of constructing some simple way to pass the files
which would be removed on to another script is a little different than
what I initially thought the patch would be useful for, namely as a
testing/debugging aid for an admin.

Perhaps both goals could be met by making use of '--debug' together
with '--dry-run'. If they are both on, then an additional message like
"pg_archivecleanup: would remove file ... " would be printed to
stderr, along with just the filename printed to stdout you already
have.
