Re: [PATCH v2 5/5] branch -d: refuse deleting a branch which is currently checked out

Kazuki Yamaguchi [off-list ref] writes:

When a branch is checked out by current working tree, deleting the
branch is forbidden. However when the branch is checked out only by
other working trees, deleting is allowed.
Use find_shared_symref() to check if the branch is in use, not just
comparing with the current working tree's HEAD.

It seems that applying this directly on top of 'maint' does fix the
issue (and applying only part of the patch for t/ illustrates the
existing breakage), so let's make it a separate topic as you hinted
in your cover letter.

Thanks.
