Objects are what the low level storage is made of. Conceptually, The merge operation doesn't work at the object level, but rather at the history graph level. You don't merge objects, you merge history. I think it is unnecessary and probably best not to mention the word "object" in this case. The alternative is to provide more detailed explanation, such as: A merge is made by joining one or more history line to the current 'HEAD' branch. Those history lines are denoted by their terminating commit. To identify them, the SHA1 name of the corresponding commit object is used, or more frequently the name of the branch or tag currently pointing at such commit objects. but while this is more correct strictly speaking as the relation between a merge and a commit object is made, I don't know if this is any more enlightening to those who ope to learn something from the reading the documentation.
