    Fix fdo#32059: Commands merge with variables
    
    Co-work with Rodolfo Ribeiro Gomes <rodolf...@gmail.com>. Thanks a lot man!
    
    Verify if there is a space before insert a new command to not merge
    variables.
    
    Also, just make atributions in EndPos when it is needed, to make this more 
clear.
