changeset 26618:8e6d5b7317e6

merge.mergestate: perform all premerges before any merges (BC) We perform all that we can non-interactively before prompting the user for input via their merge tool. This allows for a maximally consistent state when the user is first prompted. The test output changes indicate the actual behavior change happening.
