Is "merge to feature branch" and "merge from feature branch" really
the same operation though?
The way I see it, the first is saying "take revisions that represent
development on trunk and move them to the feature branch; I will need
to resolve conflicts (both textual and semantic)".
The second is saying "my feature branch right now is exactly what
trunk ought to be. Make trunk look like my feature branch does now".
(Another way of looking at it is: the first is saying "integrate
changes from the trunk line of development into the feature line of
development"; the second is saying "this thing we used to call the
'feature line' should now be called the 'trunk line'".)
Today's merge-tracking achieves the first goal well. The operation
accomplished by 2-URL merge today achieves the second goal. Now, the
UI for 2-URL merge in the feature-branch-back-to-trunk case is
frustrating. But I think all the information exists to calculate the
correct revs and such for the 2-URL merge operation, *today*. Perhaps
all we need is a better UI around "merge-back-to-trunk", powered by
