That is somewhat unusual.
When we need to deal with arbitrary strings (like pathnames), other
parts of the system usually give the user two interfaces, --stdin
with and without -z, and the strings are C-quoted when run without
the -z option, and terminated with NUL when run with the -z option.

What is -- doing here? refs given to update-ref begin with refs/
(otherwise it is HEAD), no?
