Still haven't managed to work out how to show a usable link through
to geminispace in the gophermap.

Task for another day!

Has proved to be an issue with the view via Lagrange,
on various platforms, rather than an issue with the
gophermap. Works as expected via Floodgap.

And now fixed with release of Lagrange 1.3.0
