         * imach.c (Module): Fix bug on quitting after result lines!  
         (Module): Version 0.99r21          * imach.c: With products of covariates (age or dummies or
           quantitatives), estimates of parameters were good but when
 2021-02-12  Nicolas Brouard   <brouard@ined.fr>          estimating variances the positions of newly created covariates
           were wrongly assigned and results were wrong. Thank to Feinua_Sun!

         prevforecast=1 yearsfproj=15.3 mobil_average=0  
         or          * imach.c (Module): Fixed covariates (dummy or quantitative)

         or          program quits. Standard deviations of fixed covariates were
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          wrongly computed. Mean and standard deviations of time varying
         or          covariates are still not computed.
