Subject: function args must not use .Ar and EDOM and ERANGE require .Er;
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=1c7c1e02dc27bdb87a106695fcd64d107e077f53;p=openbsd

function args must not use .Ar and EDOM and ERANGE require .Er;
mostly mechanical diff similar to what Emil Engler just sent for sqrt(3)
