If the destination filesystem is case *preserving* (which in this case it is), surely this removes the need for unnecessary quoting?
The HFS+ file system is case preserving, but case insensitive. E.g. a file name "SomeFile" will overwrite a file named "somefile", so these two filenames cannot coexist.
Imagine that the source has a file system that is case sensitive, so it could have both those file names. If the user does a backup onto an HFS+ volume we have a problem unless we somehow deal with the case issue. Rdiff-backup deals with this by quoting the upper case characters. However, it does it in some situations where it is not necessary, i.e. if both the source and destination are HFS+.
