labels in .horizontal-form at small widths closer to the inputs below

Created by: ds125v

If you compare the two example forms in the documentation at these links:

http://getbootstrap.com/css/#forms-example

http://getbootstrap.com/css/#forms-horizontal

At smaller screen widths, when both are stacked vertically, I would have expected them to look roughly the same (ignoring the fact that one has a file input that the other doesn't). They mostly do, but the labels in the .form-horizontal are much closer to the input below them than in the basic example (which I personally think looks better) .

Perhaps these lines, which set the bottom-margin to zero on the labels as well as some other stuff, are slightly too broad and can be tweaked so they don't affect this situation?
