God dammit, I just answered this. Did you have something else to add? Was my answer not clear enough?
I'll add to it that while this may not apply here since the add-on is simple and as many pointed out "durr it works rite so who cares," if an add-on does have a problem and no one can read it, no one can fix it. Unless you'd like to make a case for an exact level of simplicity beyond which it's okay to forget up your add-on for no reason, I maintain that cutting out all the spacing in an add-on is a terrible thing and you should never loving do it.
