But it is tricky (not from implementation but from semantics point
of view) to make rev-parse follow that "-- separates revs and paths"
rule literally.  The primary use of rev-parse is to convert revs in
extended SHA-1 expressions into concrete object names, so that
scripts do not have to worry about having to deal with object names
in a format that is not 40-hexdecimal.  "git rev-parse foobar --"
that gives


without any error, because 'foobar' cannot be made into an object
name, would be behaving in a way unexpected by the calling script,
