Subject: Teach rebase -i to honor pre-rebase hook
X-Git-Tag: v1.6.0.3~35
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=d70b4a8f4ba79fb83dc95e9483f9fb3feaf578b7;p=git.git

Teach rebase -i to honor pre-rebase hook

The original git-rebase honored pre-rebase hook so that public branches
can be protected from getting rebased, but rebase --interactive ignored
the hook entirely.  This fixes it.
