It has the reverse: there is a command to change directories that you
can intersperse with the directory names.  This makes it possible to
make it look like files from distant directories have the same parent.
To create an artificial hierarchy on a tape, the "prefix" directories
would have to exist, though not necessarily in the locations apparent
on the tape.  Leading '/'s are stripped (unconditionally) on both
saves and restores.  I'd prefer an option, perhaps with the ability
to specify how many leading directory names to strip.
