As a safeguard, checking out a branch already checked out by a different worktree is disallowed. This behavior can be overridden with --ignore-other-worktrees, however, this option is neither obvious nor particularly discoverable. As a common safeguard override, --force is more likely to come to mind. Therefore, overload it to also suppress the check for a branch already checked out elsewhere. Signed-off-by: Eric Sunshine <sunshine@xxxxxxxxxxxxxx> --- I plopped this patch at the end of the series so that it can be dropped easily if desired since Junio indicated[1] that he would "moderately object" to this change.
