Fix two regressions introduced with r26192 (FS#10976 - make the
<Untagged> string translatable):

* The translation was done too early: before the tagnavi format
  clauses were checked.  This prevented comparisons against
  "<Untagged>" when a non-English translation was active.

* The code overwrote the buffer containing the constant string
  "<Untagged>" with the translation.  This is neither safe nor
  necessary: The result pointer simply can be swapped with a pointer
  to the translation.
