1. Duplicating an empty array should always return a null array.  Otherwise,
you'd have to allocate space to store 0 data bytes in order for the result to
be non-null.

2. String literals have a null character implicitly appended to them by the
compiler.  This is done to ease calling c functions.  So a string literal's
pointer cannot be null, since it has to point to a static zero byte.

The spec identifies specifically item 2 here:
http://www.digitalmars.com/d/1.0/arrays.html#strings

see the section describing "C's printf and Strings"

I could not find a reference for item 1, but I remember reading something about
it.  Regardless of it is identified specifically in the spec or not, it is not
a bug, as the alternative would be to allocate blocks for 0-sized arrays.
