Kevin's analysis seems correct to me. The bash behavior, modulo
any (just-corrected) bugs, should reflect that interpretation. I'm not
sure how an alternate interpretation can be rationalized.

Maybe, maybe not. It's a bug, and there will eventually be a fixed
version of bash released. It's existed since at least bash-2.05b,
the earliest version of bash I have handy, so that should give you an
idea of how many times it's come up in the last five years or so.
