Reading in the file takes longer: about a second and a half. So... this is not a problem any more, it seems -- at least not with plain ASCII files. So I will let this be. |

(The effective speedup was achieved with version 3.0. Reading in a file became faster, but also the handling of pure ASCII text became much faster.)
