From 1b5735f75c7fd5a46a86adce35d1ed0c6e00ee0f Mon Sep 17 00:00:00 2001 From: Elijah Newren Date: Sat, 11 Apr 2020 02:44:24 +0000 Subject: [PATCH] rebase -i: mark commits that begin empty in todo editor While many users who intentionally create empty commits do not want them thrown away by a rebase, there are third-party tools that generate empty commits that a user might not want. In the past, users have used rebase to get rid of such commits (a side-effect of the fact that the --apply backend is not currently capable of keeping them). While such users could fire up an interactive rebase and just remove the lines corresponding to empty commits, that might be difficult if the third-party tool generates many of them. Simplify this task for users by marking such lines with a suffix of " # empty" in the todo list.
