Is that "option no-deref" really necessary when deleting refs? Does
it have any effect at all?
The synopsis in 'git update-ref's manpage indicates that '--no-deref'
is only applicable when updating a ref, but not when deleting one;
though the usage shown by 'git update-ref -h' doesn't indicate this.
Anyway, it appears that when deleting refs no symref dereferencing is
performed and '--no-deref' is simply ignored:
$ git branch one
$ git branch two
$ git symbolic-ref ONE refs/heads/one
$ git symbolic-ref TWO refs/heads/two
$ cat .git/{ONE,TWO}
ref: refs/heads/one
ref: refs/heads/two
$ git update-ref -d ONE
$ git update-ref --no-deref -d TWO
$ cat .git/{ONE,TWO}
cat: .git/ONE: No such file or directory
cat: .git/TWO: No such file or directory
$ git for-each-ref
