Fix "git log --diff-filter" bug

Browse Source 
In commit b7bb760d5ed4881422673d32f869d140221d3564 (Fix revision
log diff setup, avoid unnecessary diff generation) an optimization was
made to avoid unnecessary diff generation.  This was partly fixed in
99516e35d096f41e7133cacde8fbed8ee9a3ecd0 (Fix embarrassing "git log
--follow" bug).  The '--diff-filter' option also needs the diff machinery
in action.
