If the user wants to edit a read-only file in a tgz owned by himself,
why can he not _chmod_ the file and _then_ edit it?
That said, I would _usually_ prefer that when I enter a tgz, that I
see all component files having the same uid/gid/permissions as the tgz
file itself - the same as I'd see if I entered a zip file.
