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-@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 ...
