Trent, instead of going with a gyp include file, please, could you fold it
directly here? I know it is kind of big, but I think it will be better to keep
everything in this file together.

I think that would have a negative impact. 10 levels of indent is a bit nuts.
Decomposition is generally good. As is consistency (in this case with the same
pattern at
https://code.google.com/p/chromium/codesearch#chromium/src/chrome/chrome_dll....
). And since the goal of ui_unittests_bundle.gypi is to mock out the same thing
provided by chrome_dll_bundle.gypi, consistency is important.
