Bug#658562: format usage more standardly

[jidanni at jidanni.org]

Package: libgeo-distance-perl
Version: 0.17-1
Severity: wishlist
File: /usr/share/man/man3/Geo::Distance.3pm.gz

Please write
         my $distance = $geo->distance( 'unit_type', $lon1,$lat1 => $lon2,$lat2 );
better as
         my $distance = $geo->distance( 'unit_type', $lon1, $lat1 => $lon2, $lat2 );
to be clearer, as both
print $geo->distance( 'meter',  22,44 => 23,45 );
print $geo->distance( 'meter', "22,44" => "23,45" );
give "valid" answers.
