Reduce shellcheck warnings about missing {} for possible array dereference. Make sure we are not loosing error code when assigning local vars and explicitely ignore 'errors' from standalone lines when needed. Add some missing quotes. Use $() instead of ancient `` Avoid writing some temporary data into /tmp - test need to store files within its own 'testdir' - so it can be properly discarded.
