/* 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 ;)
