sed 3.02-11 fails to distinguish between [A-Z] and [a-z]

[Jake Fan]

Hello,

One of my bash scripts reported a strange error on Mandrake 8.0 Linux, 
which led to the discovery of this bug in sed 3.02-11.  It appears that it 
is incapable of distinguishing between [A-Z] and [a-z].  Simply do the 
following command line:

echo gnu | sed 's/[A-Z]//g'

And the result is not what it's supposed to be.

Version 3.02-9 and earlier appear to work ok.

Regards,

Jake Fan
