; ELSE - extra test to check the comment starting at beginning of line is safe

        ; v1.18.2 didn't find nested IFNDEF inside false-block, because of label in front of it
        ; causing the ELSE to be processed for IFDEF BORDER, making the blocks incorrect:

        ; the fix works only for user not using --dirbol, and still fails for temporary labels (the number-ones)
        ; (just split it into two lines then, temporary/normal label on one line, IF/IFDEF/ELSE/... on next line)
