I agree. vim recognises a bare ] properly, and I do a lot of my
regexp testing in vim (perhaps not a good idea, but...). vim, in
fact, recognises /[/, /[]/, and /]/ as valid character searches.
/[]]/ is the same as /]/ or /[\]]/. I'm not sure how hard this would
be, but aside from /[]]/, I don't think that any of these
would/should be problematic.
