| /* Win32 Exceptions: |
| * |
| * Note that trailing spaces and trailing periods are never recorded |
| * in the file system, except by a very obscure bug where any file |
| * that is created with a trailing space or period, followed by the |
| * ':' stream designator on an NTFS volume can never be accessed again. |
| * In other words, don't ever accept them when designating a stream! |
| * |
| * An interesting side effect is that two or three periods are both |
| * treated as the parent directory, although the fourth and on are |
| * not [strongly suggest all trailing periods are trimmed off, or |
| * down to two if there are no other characters.] |
| * |
| * Leading spaces and periods are accepted, however. |
| * The * ? < > codes all have wildcard side effects |
| * The " / \ : are exclusively component separator tokens |
| * The system doesn't accept | for any (known) purpose |
| * Oddly, \x7f _is_ acceptable ;) |
