This could be further enhanced for compatibility with those 'witless morons'
that parse the existing output of Mercurial in plural form:

     u = t.ungettext(singular, plural, n)
     encoded = _encode(u, message)
     if n == 1 and encoded == singular:
         encoded = plural
     return encoded

Perhaps, there could be a configuration setting, say 'plurals = true' to
turn compatibility mode off.

I'll recent the patch if either solution is acceptable.
