"Visual Diff" button in Hg log viewer
Created originally on Bitbucket by yruslan (Ruslan Yushchenko)
The new "Hg log file viewer" feature is great for comparing arbitrary file revisions. But often is is desirable to use external tool like Kdiff3 or WinMerge to view the difference. It would be nice to add the button to the toolbar or/and to right click menu.
