There are a lot of refactoring patches where people change camel case
names to kernel style names etc.  I've written a script to make it
easier to review them.  It's attached.

For example the linked patch is about 7900 lines long.  It renames
A_BOOL to bool, TRUE to true and FALSE to false.

cat email.txt | ./rename_rev.pl A_BOOL bool TRUE true FALSE false | less

The resulting diff is 78 lines long (99% reduced).  Woohoo!
