The 'msgid' were updated to ensure gettext will find them, and the
translation have been updated too to stay in line with the message
(within the limits of google translate's help, because I don't speak all
these languages).

A few internationalized format strings have only one %s in the default
while two strings are being passed. Change those defaults to have two
%s's, which means we also have to update the .po files to match. May as
well throw in the extra %s in the translated version while we're at it.
