Spaces in distname no longer work

[ryandesign (Ryan Carsten Schmidt)]

I assume MacPorts used to support values of distname containing spaces because the mandelbrot-set-viewer port was added having this line:

distname            Mandelbrot Set Viewer ${version}

The current version of MacPorts at that time was 2.3.1. MacPorts 2.7.1 however tries to fetch four separate distfiles ("Mandelbrot", "Set", "Viewer", and "5.01.zip").

--->  Attempting to fetch Mandelbrot from http://www.geometrian.com/data/programming/projects/Mandelbrot%20Set/Viewer%205.01/

Quoting it doesn't work either:

distname            "Mandelbrot Set Viewer ${version}"

$ port distf
--->  Distfiles for mandelbrot-set-viewer
Error: Failed to distfiles mandelbrot-set-viewer: list element in braces followed by ".zip" instead of space

I didn't find any other Portfiles using spaces in distname and I expect I'll work around this problem as I update this port to a newer version but base should support distfiles having spaces in their names.

Handle distname containing spaces

A simpler workaround would be to set distfiles to "${distname}${extract.suffix}" directly.
