Since array types are handled differently, errors referencing them also need to be handled differently. Add and use a new INVALID_ARRAY_SPEC error. Also add INVALID_CMD and INVALID_DYN_CMD to catch and display the correct form for badly-formed commands, which can also be used in place of CMD_INCOMPLETE, which is removed, and remove CMD_TOO_LONG, since it's no longer used.
