Words ending with e (es)

What do you think about these cases? I don't know how, or if it's possible, to prepare a rule for them, so I'm just submitting the failing test.

    test_palabras_terminadas_en_e(TestSpanishInflections) [/inflections/test/es_test.rb:37]:
    Expected: "pasaje"
      Actual: "pasaj"

I'm ok with specifing those in the application inflections initializer, but just in case there is a common rule out there..
