* New test scripts exercise some basic functionality
* Most header inclusions are now protected (portability)
* read.c now relies on security checks in libarchive instead
of trying to do its own (optimization)
* -p now enabled by default for root, add --no-same-permissions
to disable it
* Comments, minor style fixes.
