You'd need read-symlink to create a tar archiver. Providing it is also
more in line with Scheme tradition, because with read-symlink you can
implement real-path, but with real-path you cannot implement
read-symlink.

The Linux kernel provides readlink() and not realpath(). While it's
probably good to provide real-path as well, I would prefer removing that
one if only one could be kept.
