Fix bug with alternate linked directories

Browse source 
Previously the tracked files were sorted, and then the files and their
parent directories were considered for possible alternates. Depending on
the length of directories and names of files, inconsistencies would
occur because the directory separator (/) would be part of the sorting.

To fix this, a unique list of tracked files and their parent directories
are sorted into a single list which is processed.
