more /? of spaces

Restore the ability to look up a single space by 'name'.

I thought mungspaces("<all spaces>") kept one space, but it doesn't.
It's a lucky accident that unnaming monsters and objects still works.
There may be other places which intend to give a special meaning to
a single space that don't still work....
