Fix a very subtle gotcha in the pkgdef definition.

If the last (or only) section in a pkgdef file didn't end with a blank
line then the 'section end' actions wouldn't be performed.
The 'section end' marker is still a *single* blank line and if there are
multiple sections in a pkgdef they *must* be seperated by such a line.
