omit unnecessary nargout checks * paramdemo.cc, __ichol__.cc, __ilu__.cc, balance.cc, dassl.cc, eig.cc, ellipj.cc, filter.cc, givens.cc, hess.cc, lsode.cc, lu.cc, mgorth.cc, nproc.cc, pr-output.cc, quad.cc, quadcc.cc, sylvester.cc, urlwrite.cc, variables.cc, ccolamd.cc, colamd.cc, qr.cc: Don't call print_usage based on value of nargout. If nargout doesn't alter function behavior and returning extra values is inexpensive, simply return them instead of checking nargout.
