Oh, look, though the manpage says:

   <pattern>...
       If one or more patterns are given, only refs are shown that match
       against at least one pattern, either using fnmatch(3) or literally,

'git for-each-ref' does in fact understand double asterisks:

   $ git for-each-ref --format='%(refname)' '**/master'
   refs/heads/master
   refs/remotes/github/master
   refs/remotes/origin/master
   $ git for-each-ref --format='%(refname)' 'refs/heads/b/**'
   refs/heads/b/r/a/n/c/h

Great, this combined with refname:strip=2 and 3 might open up some more optimization possibilities...
