Hi, I had a particular notion of what rebase -X subtree would do but I am apparently mistaken. What should be the result of the script below? I expected commits to be replayed on top of master with their trees adjusted to move files into a "files" directory. In the first case, the rebase seems to have done nothing. In the second case I get an error: First, rewinding head to replay your work on top of it... fatal: Could not parse object '6c0826e4cf4b1f44ebafbd4084c1f0066a59d112^' Unknown exit code (128) from command: git-merge-recursive 6c0826e4cf4b1f44ebafbd4084c1f0066a 59d112^ -- HEAD 6c0826e4cf4b1f44ebafbd4084c1f0066a59d112 If "files" exists and I use rebase -X subtree it replays the commits, moving trees out from under "files," as I would expect. Is it not possible to use git rebase to move trees under a new subdirectory? I know that I can use filter-branch to accomplish what I want, I'm just curious whether git rebase is expected to behave as I thought. At the very least, it seems a better error message in the orphan branch case would be helpful.
