Comparing different files in different revisions
Created originally on Bitbucket by rlegendi (Richard Oliver Legendi)
It would be awesome to compare file.a in revision x with file.b in revision y with the HgEclipse plugin.
At the moment the best way to do that is to "Revert" on the two files and then "Compare with each other".
I believe this is a commonly used feature on merging changes on a renamed file.
