Actually ...

It seems that Text::Wrap::fill() was added between 5.004_04 and
5.004_05.  I had not realized that the former was an official release.

We can

* Try to special-case 5.004_04 and provide the version of fill()
  indicated in the Text::Wrap documentation;

* Decide we've played enough with this and require either 5.004_05 (can
  we do this?) or 5.005.
