feature request: gentle nudges for well-formed git commit messages

[David James]

I like what Tim has to say about git commit messages:

I've noticed that gitx currently has a vertical bar to help us
remember the 50 character mark. Could we also add something similar
for the 72 character mark?

It might be worth considering using the approach using with VIM
integration:

Thanks :)
