Title: Fix entropy/printable chars bars, accurate help text, code cleanup

I think this is the expected behavior regarding blocksize for entropy and printable chars. There was a pb with printable chars for large blocks since r_print_fill expects u8 value and values were truncated. Did some cleanup and code homogenisation.

Hope this helps !
