* Note that trailing spaces and trailing periods are never recorded

* 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 ;)
