# We create two convenience archives with the same name, and _also_
# containing an object with the same name.  This is necessary to detect
# the failure with both 1.5.22 and HEAD, since the latter does not (did
# not?) remove the temporary output directory, thus masking the failure
# when all objects have distinct names.
