Add "was copied from" option to context menu
Created originally on Bitbucket by Anonymous
We have "was renamed from" option in context menu which preserves history of the files. It would be great if we had "was copied from" as well. This would prove useful especially when inspecting file history - we could see the related changesets more easily. Right now we need to do manually "hg copy --after SOURCE DEST" which isn't very user-friendly.
