The cgit archive command creates a prefix (root) directory entry
in the archive file. That entry's time is set to the commit time.
This patch makes jgit's behavior consistent with with cgit:
prefix: hoge/ -> creates prefix directory "hoge/" entry.
prefix: hoge//// -> creates prefix directory "hoge/" entry.
prefix: hoge/foo -> does not create prefix directory entry, but for
each file/directory entry, prefix is added.
