-/**
- *	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.
