completion.at: Improve portability

NetBSD's /bin/sh complains on the syntax of bash array.

While the use of eval might seem overkill, it's tricky to avoid
the error because the generated code will be a part of the surrounding
subshell and the syntax check is done a bit earlier than the execution
of these conditionals.
