Re: Support for a series of patches, i.e. patchset or changeset?

[Eric Miao <eric.y.miao@gmail.com>]

The problem is, most cases we have no idea of the base rev1, and commit rev2
which it's leading up to. E.g. for a single patch which is between
commit rev1..rev2,
how do we find out rev1 and rev2.
