ls(1) on System V

This is the second S5R2 bug that is fixed "for free" if you convert
to the Berkeley "directory library".  The library provides directory
entries with null-terminated names, fixing this bug; the previous bug
was a shell problem caused, if I remember correctly, by testing whether
the result of an "open" of a directory was > 0 rather than whether it
was >= 0.

I've converted lots of S5R2 programs to use the library; it's very easy.
I'd vote for putting it into 1) the /usr/group standard, 2) the System V
Interface Definition (which currently, bless its soul, does *not* commit
to what directories look like when you open them), and therefore 3)
System V.
