since Git 2.16.1, I've noticed a bad behaviour of git rebase -i -p. It
screws up merge commits created with --log (or config merge.log = true)
in my history. A good merge commit with message like:
Merge branch 'test'
* test:
c
b
is changed after rebase (without touching that commit in any way) into:
Merge branch 'test' a git-rebase-p-test.sh test: c b
I think we saw this problem independently discovered and a fix for
it posted today to the list.
