Subject: [PATCH v3 20/21] completion: support switch

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Fri, 8 Mar 2019 16:57:51 +0700

Completion support for --guess could be made better. If no --detach is
given, we should only provide a list of refs/heads/* and dwim ones,
not the entire ref space. But I still can't penetrate that
__git_refs() function yet.
