like [X-Y] should match all characters between X-Y according to the
locale's collating order, not by binary value. For now, this only fixes
the !MBS_SUPPORT case (which is the default).
We've already got it in libc, but both libraries are incompatible
wrt. their header files and internal data structures. This
incompatibility caused the expr(1) on the fixit floppy to mysteriously
dump core for the colon operator.
Strong 2.2 candidate, since it fixes the usage of MAKEDEV on the fixit
floppy. I'd like to get it reviewed by somebody else though.
