-/* Derived from The Open Group Base Specifications Issue 7, IEEE Std 1003.1-2008
- * as described in;
- *   http://pubs.opengroup.org/onlinepubs/9699919799/functions/fnmatch.html
- *
- * Filename pattern matches defined in section 2.13, "Pattern Matching Notation"
- * from chapter 2. "Shell Command Language"
- *   http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_13
- * where; 1. A bracket expression starting with an unquoted <circumflex> '^' 
- * character CONTINUES to specify a non-matching list; 2. an explicit <period> '.'

- * in a bracket expression matching list, e.g. "[.abc]" does NOT match a leading 
- * <period> in a filename; 3. a <left-square-bracket> '[' which does not introduce
- * a valid bracket expression is treated as an ordinary character; 4. a differing
- * number of consecutive slashes within pattern and string will NOT match;
- * 5. a trailing '\' in FNM_ESCAPE mode is treated as an ordinary '\' character.
- *
- * Bracket expansion defined in section 9.3.5, "RE Bracket Expression",
- * from chapter 9, "Regular Expressions"
- *   http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html#tag_09_03_05
- * with no support for collating symbols, equivalence class expressions or 
- * character class expressions.  A partial range expression with a leading 
- * hyphen following a valid range expression will match only the ordinary
- * <hyphen> and the ending character (e.g. "[a-m-z]" will match characters 
- * 'a' through 'm', a <hyphen> '-', or a 'z').
- *
- * NOTE: Only POSIX/C single byte locales are correctly supported at this time.
- * Notably, non-POSIX locales with FNM_CASEFOLD produce undefined results,
- * particularly in ranges of mixed case (e.g. "[A-z]") or spanning alpha and
- * nonalpha characters within a range.
- *
- * XXX comments below indicate porting required for multi-byte character sets
- * and non-POSIX locale collation orders; requires mbr* APIs to track shift
- * state of pattern and string (rewinding pattern and string repeatedly).
- *
- * Certain parts of the code assume 0x00-0x3F are unique with any MBCS (e.g.
- * UTF-8, SHIFT-JIS, etc).  Any implementation allowing '\' as an alternate
- * path delimiter must be aware that 0x5C is NOT unique within SHIFT-JIS.
