bug#9417: digit-argument doesn't work with `key-translation-map'

[Le Wang]

repro:

1. emacs -Q
2. eval-region:

  (define-key key-translation-map [(control x)] [(control j)])
  (define-key key-translation-map [(control j)] [(control x)])

3. C-1 C-j C-f

expectation: call `find-file'
actual: call binding of C-j `eval-print-last-sexp'

Emacs version: CVS Head built today on Windows 7.

In Emacs 23, the behavior is slightly different.  C-1 C-j calls
`eval-print-last-sexp' withing the final C-f key chord.
