That would not be safe if caname had been used as a real directory name
(e.g. by chdir'ing to it), which is not the case.

It is used to ensure the order of directories in the resulting archive
is the same, whatever their order on the command line and to avoid
dumping the same directory twice, if it was referenced by different
relative names.
