No error message for `unset 'a[]''?

It's still a valid function name, and `unset' attempts to unset variables
first, then functions. POSIX leaves that unspecified; that is how bash
behaves. Bash doesn't print an error message if you try to unset a function
that doesn't exist, and this falls into that case.

I'll respond to the rest at a later time, but this was quick.
