IE7-/Win: Default vertical margin on paragraphs

Properties of default vertical margins in IE7- (to be verified...)

They are equal to 19px. Expressed in px, since they do not change when font-size is changed (either in the CSS, or using the browser's settings)
In case of an hasLayout container, the top margin of the first p, and the bottom of the last disappear. Here they behave differently from specified ones.

Properties of auto vertical margins in IE7- (to be verified...)

They are equal to 19px, the same as the 'default' ones. (This is not correct: Auto on vertical margins should become '0'.)
In case of an hasLayout container, they behave as specified ones, not as default ones.

In all the following test cases a couple of paragraphs with green background are in a container with red background (darker when it has Layout).
