maint: Replace instances of goto in liboctave where convenient. * CMatrix.cc (operator >>): Replace "goto done;" with "return is;". * CNDArray.cc (operator >>): Replace "goto done;" with "return is;". * lo-specfun.cc (gammainc (various)) : Rename return variable result to retval. Replace "goto done;" with "return XXX ();" where XXX is a container such as Matrix, NDArray, FloatMatrix, FloatNDArray. * lo-specfun.cc (gammainc (double, double, err), gammainc (float,float, err)): Move input validation to top of function. * randpoisson.c (poisson_cdf_lookup): Place action of if statement on separate line. * cmd-edit.cc (do_decode_prompt_string): Replace goto statement with break. Rename variable result to retval. Rename variable temp to tmpstr. Place cases of switch statement in mostly alphabetical order. Use single quotes when describing a single character. Use temporary number buffer of 32, not 128. * oct-sort.cc (sort): Replace "goto fail;" with "return;"
