Quoting "B. T. Raven": > As in your "count-buffer-wc-option" function below. Of course the > whole exercise can be avoided with M-| or C-x h M-| `C-x h' would be mark-whole-buffer, and M-| (pipe) shell-command-on-region. Tough that is certainly an alternative, I think `M-x words' is a lot better (on the region if there is one; otherwise, the entire buffer). So this is not an "exercise", I set it up because I intend to use it. > Since a null string is still a string you need something like > (length opts). My thought was rather - it is not even a null string if no optional arg is passed. I don't know if that is the case; but that would be easy to find out once I'm able to call the functions as intended, with or without the optional arg. -- Emanuel Berg - programmer (hire me!
