Section 5 - quitar 'un poco de'
Original player's command is a text that varies.
First after reading a command:
let N be "[the player's command]";
let pop be a indexed text;
let pop be "[the player's command]";
let pop2 be "[pop]";
now original player's command is pop2;
replace the regular expression "un poco de" in N with "";
change the text of the player's command to N.
