I made this repository to illustrate some issues I've been having with Plan9's git implementation.

Rebase Problem

Switch to branch b with:

git/branch b

Try to rebase it on top of branch a with:

git/rebase a

Notice that branch now points to the same commit as branch a. The last commit from branch b seems to have ceased to exist.

Merge Problem

Switch to branch c with:

git/branch c

Try to merge in branch a with:

git/merge a

Notice that this should have resulted in a merge conflict, but didn't.
