Is there a way to define a command like
\notsoshortintertext with two parameters to define the vertical space before and after it?
The problem I have is that
\intertext is to wide on a specific page resulting in a poor page break. And with the
\shorintertext I get an underfull vbox. So I would like to tune the vertical space at that point. I've tried to find the definition for
\shortintertext, but wasn't able to understand the quite cryptic definition in the mathtools.dtx.
