Not sure about this. See
http://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap09.html#tag_09_03_05

"The special characters '.', '*', '[', and '\' (period, asterisk,
left-bracket, and backslash, respectively) shall lose their special
meaning within a bracket expression."

So I think the original version of the test is in fact correct with a
single \ in the actual string within the bracket expression. This test
passes in a very few implementations. I might be wrong though...
