Nice approach.  :)  One remark re "Looking for .cxx files whose first 
include is not the header file...":  I did not look into the articles 
you cite to see whether or why they advocate to include the 
corresponding header first in the .cxx file (a common reason to do so is 
to ensure that the header is self contained), but note that LO requires 
that each file includes sal/config.h first thing (even if your mined 
data indicates that this rule is largely ignored).

Personally, I've grown used to sorting includes from general to 
specific, with blocks

  #include "sal/config.h"

  #include <C++-standard>---

  #include <platform>...

  #include "qualified/LO-modules"...

  #include "within-same-LO-module"...

for no real reason.
