Cannot diff between two revisions
Created originally on Bitbucket by alfonse (Jason McKesson)
You cannot create a patch file between two separate revisions in TortoiseHg 2.0. This was possible in 1.x, since you could select two revisions that were not contiguous in the repo viewer and simply do a diff on them. It would return a patch file that you could save to anywhere. That's not possible in the workbench.
