Avoid ambiguity between refname and filename in rev-parse
Avoid ambiguity between refname and filename in rev-parse

Although it really is very convenient, not requiring explicit
'-r' option to name revs is sometimes ambiguous.

Usually we allow a "--" to say where a filename starts when it
_is_ ambiguous.  However, we fail that at times. In particular,
git-rev-parse fails it.
