Anyway I'm glad the Homebrew tig is working for you. When we made \nthis change and discussed whether we needed backwards compatibility I \nthink we only discussed the possibility of git being upgrading while a \nrebase was stopped for conflict resolution, not the possibility of \npeople having two different versions of git installed and using one to \nstart a rebase and the other to continue it.\n\nBest Wishes\n\nPhillip\n\n> Regards\n> \n> \n> [0]: https://github.com/jonas/tig\n> [1]: https://nixos.org/nix/\n> \n> El mar., 19 de feb. de 2019 a la(s) 06:59, Phillip Wood\n> (phillip.wood@talktalk.net) escribió:\n>>\n>> Dear Sebastián\n>>\n>> On 19/02/2019 07:22, Eric Sunshine wrote:\n>>> [cc:+phillip.wood@talktalk.net]\n>>\n>> Thanks Eric\n>>\n>>> On Tue, Feb 19, 2019 at 1:45 AM Christian Couder\n>>> wrote:\n>>>> On Tue, Feb 19, 2019 at 5:20 AM Sebastián Mancilla wrote:\n>>>>> But since Git 2.20.x it doesn't work anymore.
