If you move a directory, fossil moves the files to the wrong directory when you the .. directory. Observe:

Pretty minor, but unexpected with large numbers of files. I'd expect `fs mv baz` to move the directory object itself under bur. Seems like an off-by-one error in terms of path resolution but I haven't looked at the code yet. I remember seeing this in practice with ../../../ as my path and I think the files ended up ../../../ and not ../../../some/sub/dir/ (don't quote me on that, it was kinda late last night when I saw this and noted the behavior). I think if you resolved the source and destination directories to absolute paths (or absolute relative to the fossil checkout) that this bug would be fixed.
