Change convention for referencing issues in commit messages?

This started life over as a comment I posted at #1059966-20: Change recommended format for commit messages (no more '#1234 by abc') but I'm moving it here at eliza411's suggestion to hopefully gather more feedback on the proposal...

Sorry I didn't suggest this sooner, but I just came up with it today while I was happily doing Git commits on a plane. ;)

Instead of:

How about this?

We're already used to referring to issues like that (or we should be), and it's less duplication when scanning logs, and less wasted horizontal space for the all-important summary line.

I don't think it's necessarily too late to change this. We're still in a transition period trying out all sorts of approaches to all sorts of things, so the "best practices" are still being discovered. I'll probably just adopt this practice for myself, (along with trying to properly credit authorship for people who contribute patches, even if it does take a tiny bit of extra work on my part and it's not the documented recommendation). But this one seems like something we could all just get behind, and is even less work than the currently documented suggestion.

Thoughts? ;)

Thanks,
