I think I found out why this "test -d" was here in the first place:

  $ ./t0000-basic.sh --debug
  [...]
  # passed all 77 test(s)
  1..77
  error: Tests passed but trash directory already removed before test cleanup; 
aborting

When --debug is in use, we do not set $remove_trash. The original was
relying on 'test -d ""' to return false.

I think this whole removal block should probably be moved inside a
conditional like:

  if test -n "$remove_trash"
  then
     ...
  fi

I also wonder if we should come up with a better name than
$remove_trash. A script which unknowingly overwrites that variable would
be disastrous.

Perhaps we should drop it entirely and just do:

  if test -z "$debug"
  then
     test -d "$TRASH_DIRECTORY" ||
     error "Tests passed but..."
  [and so forth...]
  fi
