... Is the last output really what we want? '-LZ' ends up having noeffect if there are leading spaces. Wouldn't it be more useful if theleading spaces were always removed, as '-L' promises to do, and the '-Z'then insured that leading zeros were stripped as well? That is,shouldn't the last two commands above both output '1200'? As it is, the'-Z' and the '-L' basically cancel each other.
