Re: [RFC PATCH v2] revision: new rev^-n shorthand for rev^n..rev

> I use rev^..rev daily, and I'm surely not the only one. To save typing

> The existing syntax rev^! seems like it should do the same, but it

> As a natural generalisation, we also accept rev^-n where n excludes the
> nth parent of rev, although this is expected to be generally less useful.
