check_format: compare commits against previous commit.

Browse Source 
Previously when doing the naming conventions check, we were
checking against master which was causing some weird issues on
patches which weren't rebased. The much simpler check is to just
compare each patch against the previous one.

This method still works to prevent any bad changes from getting
merged, but handles naming issues on a patch by patch basis.
