for-each-ref: utilize core.warnAmbiguousRefs for :short-format

Browse Source 
core.warnAmbiguousRefs is used to select strict mode for the
abbreviation for the ":short" format specifier of "refname" and "upstream".

In strict mode, the abbreviated ref will never trigger the
'warn_ambiguous_refs' warning. I.e. for these refs:

  refs/heads/xyzzy
  refs/tags/xyzzy

the abbreviated forms are:

  heads/xyzzy
  tags/xyzzy
