Though I must first admit that I haven't looked at the code, creating a
zero-length string is usually done when you need a valid but zero-length
buffer for a pointer to point to, as that pointer is used elsewhere with a
non-zero-length buffer.
Now, if the pointer we're talking about always points to a buffer of
length 1 and it always contains an empty string, then something is
definitely wrong. :)
