- *     glob_match - match a text string against a glob-style pattern
- *     @text: the string to be examined
- *     @pattern: the glob-style pattern to be matched against
- *
- *     Either/both of text and pattern can be empty strings.
- *
- *     Match text against a glob-style pattern, with wildcards and simple sets:
- *
- *             ?       matches any single character.
- *             *       matches any run of characters.
- *             [xyz]   matches a single character from the set: x, y, or z.
- *             [a-d]   matches a single character from the range: a, b, c, or d.
- *             [a-d0-9] matches a single character from either range.
- *
- *     The special characters ?, [, -, or *, can be matched using a set, eg. [*]
- *     Behaviour with malformed patterns is undefined, though generally reasonable.
- *
- *     Sample patterns:  "SD1?",  "SD1[0-5]",  "*R0",  "SD*1?[012]*xx"
- *
- *     This function uses one level of recursion per '*' in pattern.
- *     Since it calls _nothing_ else, and has _no_ explicit local variables,
- *     this will not cause stack problems for any reasonable use here.
- *
- *     RETURNS:
- *     0 on match, 1 otherwise.
