So that's the specific case of a missing parameter error, but is this the
only kind of error one can make with boost::locale::format?  If not, it's
not really a convincing argument that all users all the time would like
boost::locale::format to ignore all errors.  And you do qualify that this
particular error is "almost never a error", leading me to believe that
sometimes it really is an error you care about.
