From 91439928ecfcb402856dc5dffacdc36ca070d84e Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Thu, 28 May 2020 11:10:48 -0700 Subject: completion: improve handling of --orphan option of switch/checkout The --orphan option is used to create a local branch which is detached from the current history. In git switch, it always resets to the empty tree, and thus the only completion we can provide is a branch name. Follow the same rules for -c/-C (and -b/-B) when completing the argument to --orphan. In the case of git switch, after we complete the argument, there is nothing more we can complete for git switch, so do not even try. Nothing else would be valid. In the case of git checkout, --orphan takes a start point which it uses to determine the checked out tree, even though it created orphaned history. Update the previously added test cases as they are now passing.
