[Bug 1953151] [NEW] Doubled control operators before `alert` will have their second characted appear in the body of the message

[Akbarkhon Variskhanov]

Public bug reported:

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. 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$//'\'')"'
