From: Elijah Newren <redacted> As with the last commit, it feels odd to talk about "creation" (which to me implies a brand new file, i.e. one not associated with an existing file, and thus one that could not have been a rename) when we are using the files to look for renames. Use the term "addition" instead.
Hmph, to me "create" and "add" mean the same thing in all the sentences this patch updates. We first notice the differences in two trees, some paths have contents in both trees so they cannot be creation or deletion. Some paths only exist in one of the trees and they are initially labelled as "created" or "deleted". If there were no request by the caller to detect renames, then that's the end of the story. Only after we match up a path in the new tree that did not exist in the old tree with another path in the old tree that no longer exists in the new tree, what initially got labelled as creation of one and deletion of another may become a rename. And in the above two paragraphs, if I replace "to create" with "to add" and "to delete" with "to remove", I do not see how the story becomes more natural or logical or intuitive. Perhaps I am not getting the subtle difference you find in these two words? This looks like a totally meaningless churn to me.
