31  * Verify that the pattern matcher implements the wildcard logic specified
32  * in SUSv2 for the cpio command.  This is essentially the
33  * shell glob syntax:
34  *   * - matches any sequence of chars, including '/'
35  *   ? - matches any single char, including '/'
36  *   [...] - matches any of a set of chars, '-' specifies a range,
37  *        initial '!' is undefined
38  *
39  * The specification in SUSv2 is a bit incomplete, I assume the following:
40  *   Trailing '-' in [...] is not special.
41  *
42  * TODO: Figure out if there's a good way to extend this to handle
43  * Windows paths that use '\' as a path separator.  <sigh>
