Not sure myself. I probably wanted visibility, and somehow ended
up using different presentations.

Without this the _automatically_ generated names for cloned repositories
have all the whitespace around them. As you cannot sanely depend on
automatically
generated names, I thought that making them simpler will make sense.

But I should complete the patch: remove heading whitespace, and replace
multiple spaces and control characters with one space.
