Details:

The 'end' keyword breaks proper code folding when used as an index to an
array:


a = 1:5;
if true
    a(1:2)+=3;
    a(3:end)-=3; %code fold matched with if
    b = a;
    for i=1:3
        b+=1;
        if false
            b=3;
            b = a(end); %code fold matched with if
            q = b;
        endif 
        a = 1;
    endfor
    c+3;
endif
a = 1:5;
if true
    a(1:2)+=3;
endif


Each 'end' used as an index will be matched improperly with the prior control
statement, and won't be collapsed completely. Surrounding and following lines
are shown to match to the wrong end statements, or for the last 'if' doesn't
show any match lines, but still folds.
