Re: [PATCH v5] revision: new rev^-n shorthand for rev^n..rev

> "git log rev^..rev" is commonly used to show all work done on and merged
> from a side branch. This patch introduces a shorthand "rev^-" for this
> and additionally allows "rev^-$n" to mean "reachable from rev, excluding
> what is reachable from the nth parent of rev". For example, for a
> two-parent merge, you can use rev^-2 to get the set of commits which were
