If I run an interactive rebase on a branch without the --root flag, git
does not modify (change the hash, etc.) any initial commits that are
being "pick"ed in the same order. However, if I use --root, every single
commit is modified.
Here's an example:
* Old (immediately after running "git rebase -i --root"):
pick d89 root
pick 3e7 bar
pick 57e baz
* New (after editing the "git-rebase-todo" file):
pick d89 root
pick 57e baz
pick 3e7 bar
After this, AFAIK, only baz and bar's hashes should change. However, the
root commit's hash (d89) also changes.
A simpler way to reproduce this is to just run `git rebase -i --root`
and rebase without changing anything. Every commit will be modified.
Is this supposed to happen?
