The 'original' string entry in a pathspec_item is only duplicated some of the time, instead always make a copy of the original and take ownership of the memory. Since both 'match' and 'original' string entries in a pathspec_item are owned by the pathspec struct, they need to be freed when clearing the pathspec struct (in 'clear_pathspec()') and duplicated when copying the pathspec struct (in 'copy_pathspec()'). Also change the type of 'match' and 'original' to 'char *' in order to more explicitly show the ownership of the memory.
