Byte index of rightmost whole delimiter character.
function LastDelimiter(const Delimiters: AnsiString; const S: AnsiString): Integer; overload;
int LastDelimiter(const AnsiString Delimiters, const AnsiString S);
LastDelimiter returns the byte index in S of the rightmost whole character that matches any character in the Delimiters parameter (except null (#0)). S may contain multibyte characters. Delimiters must contain only single byte, non-null characters.
For example, LastDelimiter('\.:', 'c:\filename.ext') returns 12.
