command1 || command2
command2 is executed if and only if command1 returns a non-zero
exit status. The return status of AND and OR lists is the exit
status of the last command executed in the list.
The exit status of c1&&c2 is that of the last command executed in the
list. When c1 returns a non null status, then c2 is not executed then
the status of c1&&c2 is that of c1. Hence you can append ||c3 and have
