While this feature would be a good addition, more often than not I need
to look behind the latest commit regardless of whether or not it's a
trivial one.

So what I often end up doing is a `git blame --incremental`:

  git blame --incremental -L100,+6 file.c | grep -o -e '^[0-9a-f]\{40\}'

This can be fed to `git log --stdin --oneline --no-walk` for more
user-friendliness.

Of course you could just do:

  git log -L100,+6:file.c --oneline --no-patch

But for some reason that's much slower on my system.

Cheers.
