Fine. 1003.2-1992, section 3.9.1 (Simple Commands), page 136.
``If there is a command name, execution shall continue as described
in 18.104.22.168. If there is no command name, but the command contained
a command substitution, the command shall complete with the exit
status of the last command substitution performed. Otherwise, the
command shall complete with a zero exit status.''
