[Freeciv-Dev] po/check_po.pl reports correct input as error

[Erik Sigra <sigra@xxxxxxx>]

check_po.pl reports:
  msgid "* Must end turn in a city or next to land, or has a 50%% risk of 
being lost at sea."
  msgstr "* Måste avsluta sin omgång i en stad eller intill land. Löper 
annars 50%%s risk att gå förlorad till sjöss."
*** Format number mismatch for %s [msgstr:1]


But the text is displayed correctly in the client as "* Måste avsluta sin 
omgång i en stad eller intill land. Löper annars 50%s risk att gå förlorad 
till sjöss."

I don't know any other way to get the desired output so I can't please the 
current check_po.pl so it must be changed.
