From 73fdc535d269ba1ac25cdb832d72d47abdede049 Mon Sep 17 00:00:00 2001 From: Phillip Wood Date: Wed, 17 Apr 2019 15:30:41 +0100 Subject: [PATCH] rebase -i: use struct rebase_options to parse args In order to run `rebase -i` without forking `rebase--interactive` it will be convenient to use the same structure when parsing the options in cmd_rebase() and cmd_rebase__interactive().
