Howdy Nick!

Of course as soon as I asserted that this was not a bug, a little part of my 
brain told me that every time I do that, it turns out to be a bug. Software 
engineering is funny that way! ;-)

I have entered this in our new issue database and it turns out to be the 100th 
issue in the netCDF database. In celebration of this you may have as many free 
copies of netCDF as you wish.

If you want to track this, see here:
https://www.unidata.ucar.edu/jira/browse/NCF-100

You can also register if you have a comment. I suspect this will be fixed 
before the next release...

What I don't understand is why this was never found before. I will have to take 
a look at the tests to see why we didn't catch this one.

Thanks, and keep on netCDFing!

Ed
