While I do not mind seeing a patch that loosens the condition ONLY when the merge will cleanly auto-resolve without end-user interaction, when any paths conflict and require editing by the end-user, it is pretty much essential to require that the index matches HEAD to keep "git merge" usable. This is because the final step to conclude such an "automated procedure cannot cleanly resolve, so the end user helps resolving with the editor and mark the resolved paths with 'git add' or 'git rm'" session will become very error prone if we did not have the requirement. Not just the user MUST remember not to use "commit -a" or "git add" a path that was already dirty in the working tree before the merge started (which is the consequence of the current requirement, which allows local changes to the unrelated working tree files), they must MUST remember to somehow EXCLUDE the changes already registered for unrelted paths from the concluded merge.
