Create a new _BuildSectionData() to hold the code that is now in GetData(), so that it is clearly separated from entry.GetData() base function.
Separate out the 'pad-before' processing to make this easier to understand.
Unfortunately this breaks the testDual test. Rather than squash several patches into an un-reviewable glob, disable the test for now.
