Description:
        After registering trap handlers, 'trap | cat' does not deliver any
        output ('trap' does).

Each element of a pipeline is run in a separate process.  The subshell
forked to run each element does not inherit traps from its parent --
disposition of trapped signals is reset to the default.  This is as Posix
specifies.
