createdb default arguments

createdb has lost its ability to supply a default database name, and
now *requires* an argument to run. Did we make this change because it
was difficult or impossible to get the default argument on some of our
supported platforms? Or did we make the change because it is "more
correct" or something?

I'm finding it annoying to retrain my fingers to type more stuff to
get the same functionality as before ;)
