Changes the behavior of --ignore-joins to always consider a subtree add commit, and ignore only splits and squashes. The --ignore-joins option is documented to ignore prior --rejoin commits. However, it additionally ignored subtree add commits generated when a subtree was initially added to a repo. Due to the logic which determines whether a commit is a mainline commit or a subtree commit (namely, the presence or absence of content in the subtree prefix) this causes commits before the initial add to appear to be part of the subtree. An --ignore-joins split would therefore consider those commits part of the subtree history and include them at the beginning of the synthetic history, causing the resulting hashes to be incorrect for all later commits.
