We review tons and tons of mechanical patches in staging and one thing
which helps is my rename_rev.pl script.  I should put in in a git
archive somewhere.  Anyway, attached.  It tries to strip away mechanical
changes so that I can review interesting parts.

cat patch.txt | rename_rev.pl <options>

-a # detect renames automaricall
-e 's/foo\((.*?),.*)/bar($1)/  # do a perl substitution
-ea 's/[\{\\}]//g' # remove every curly brace in the diff
-r NULL # change "foo == NULL" to "if (!foo)"
-nc # ignore changes to comments
