    environment: Restore action for SIGPIPE.
    
    Code in `ui.scm' in `initialize-guix' procedure changes the handling of
    SIGPIPE to SIG_IGN.  So restore the handling to SIG_DFL so that process
    executed will have the usual action.  Technically we should record what the
    handling was, and restore it to the previous value, but that would be much
    more invasive change.
    
    Always setting it to SIG_DFL is at least less surprising than always setting
    to SIG_IGN.
    
    * guix/scripts/environment.scm (launch-environment): Restore default action
    for SIGPIPE.
