The spaces prefixing the folder names are apparently a convenience for
posting aesthetically pleasing url paths to places in our files area.
Those spaces are intentionally there, in some of the folder
(directory) names, to group the important folders near the top of the
(alphabetical) listing, on the group's website.
I think that was Helmut's doing, but he is one of a few group
moderators so it might be one of the others too.
