If you are using linux, here is git diff command I use to find leftover 
debug statements.  I imagine the -S option will work the same in git 
log.  I pipe the results into grep to filter the results to show only 
the additions. (I'm using git 1.7.1)

$ git diff --unified=0 -S"DEBUG" <commit> <commit> -- <path> | grep -e 
"diff --" -e "+" | grep -v -e "@@" -e "+++"

maybe you will find this helpful.
