But if in future we add more options for non-switching-branch checkout, we need to update both places, here and near the end of cmd_checkout(). Perhaps we can move all this block inside checkout_branch() so we only need to test "opts->patch_mode || opts->pathspec.nr" once, at the end of cmd_checkout(). Something like below? I'm not opposed to your change, but if you go with it, you should cherry pick my test in the below patch.

Sorry for late reply, but I think your change is much better than mine so I'd suggest just using that instead. ^ permalink raw reply [flat|nested] 5+ messages in thread

Yeah, I agree that having this check in parse_branchname_arg() does not make any sense, as that function is still trying to decide if we are switching to a different branch or not. The new location looks much more sensible. Will queue this on nd/multiple-work-trees (which has been in 'master' for about a month). Good thing that we caught it before it got in any tagged release.
