Comment (by vern):

 The approach of expanding like this will often work fine, but there are
 cases where it needs extra work for strict correctness.  For example,
 consider [5-M] - this needs to become [5- at A-Ma-m], presumably.  While such
 a character class range likely will almost never be used, if we care about
 the behavior being fully solid, we need to address it.  (Hmmm, and uglier
 would be [5-a].  This includes A-Z within it; does it now include a-z
 too?)

 There's also a lingering ugliness concerning the definition of case
 sensitivity for non-ASCII character sets, though presumably we don't want
 to go there regardless ...
