Pull up following revision(s) (requested by kre in ticket #907):

bin/sh/expand.c: revision 1.122

When matching a char class ([[:name:]]) in a pattern (for filename
expansion, case patterrns, etc) do not force '[' to be a member of
every class.

Before this fix, try:

case [ in [[:alpha:]]) echo Huh\?;; esac

XXX pullup-8    (Perhaps -7 as well, though that shell version has
much more relevant bugs than this one.)  This bug is not in -6 as
that has no charclass support.
