`[[' and `]]' are reserved words, and `']]' is recognized as a reserved
word if it appears in a command position, with the provision that after a
`[[', what's between the brackets is a conditional command, with its own
grammar rules, so operators like `;' will cause a parse error.

This is similar to `{' and `}'.
