This segfault only happens when cloning an empty repository and only with option
"--single-branch". Or do I miss something?
If we call "git clone" for a non-empty repository with a non-existing branch
using "[--single-branch] --branch foo" then Git will abort with a message that
the branch doesn't exist in upstream.
In an empty upstream repo the branch doesn't exist, either. So why not
abort with
the same message? That would be consistent. Otherwise I'd just
override the options
"--single-branch" and "--branch" to "not set".
