     * We are going to use GetFullPathName() to properly determine the actual

     * strips parts of the file name component in case the pattern contains
     * path specification with trailing dots, it is required to perform a
     * pre-treatment on the pattern and a post-treatment on the obtained path.
     * This is mandatory in order to use the correct file search criterion.
     *
     * One particular case is when the pattern specifies a dots-only directory
     * followed by either the "." or ".." special directories. In this case the
     * GetFullPathName() function may completely miss the dots-only directory.
     * An example is given by the pattern (C-string notation) "\\...\\." .
     * To cope with this problem we need to partially canonicalize the pattern
     * by collapsing any "." or ".." special directory that immediately follows
     * a dots-only directory. We collapse in addition consecutive backslashes.
     *
     * Finally, trailing dots are skipped by GetFullPathName(). Therefore
     * a pattern that matches files with no extension, for example: "*." ,
     * or: "dir\\noextfile." , are reduced to simply "*" or "dir\\noextfile",
     * that match files with extensions. Or, a pattern specifying a trailing
     * dots-only directory: "dir\\..." gets completely ignored and only the
     * full path to "dir" is returned.
     * To fix this second problem we need to restore the last part of the path
     * pattern using the pattern that has been first partially canonicalized.
