Revert the header-sorting patch

Andreas Schwab and John Baldwin pointed out some bugs in the header
sorting patch; and I noticed that the output was not correct when
limited to a subset of files (a bug in my script).

So, I'm reverting the patch.  I may try again after fixing the issues
pointed out.
