Fill in branch names in the merge dialog
Created originally on Bitbucket by Anonymous
There is a lot of merging going on in TortoiseHg, but the standard comment for a merge commit is just 'merge'.
It would be great if the dialog could complete the commit message with the branches involved in the merge like 'Merge branch_a with branch_b' or 'Merge with local' so we do not need to do this ourselves. This makes the timeline much more readable.
