** Description changed:

  Separating the first part of a list and the `alert` part with && (or any
  of the doubled control operators) will result the second character to be
  printed in the body of a message, for example:
  
  sleep 5s && alert
+ 
+ will display the following message:
+ 
+ sleep 5s &
  
  Adding the asterisk after the [;&|] bracket expression fixes it:
  
  alias alert='notify-send --urgency=low -i "$([ $? = 0 ] && echo terminal
  || echo error)" "$(history|tail -n1|sed -e
  '\''s/^\s*[0-9]\+\s*//;s/[;&|]*\s*alert$//'\'')"'
