A couple of quick notes on the new `vn' distribution:

(1) If you do not define `tmpnam.o' in the Makefile's EXTRAOBJS *on* *a* *Sun*,
    you will be sorry.  It appears that Sun's implementation of the `tmpnam'
    function is broken.  There should probably be a mention of this in the
    Makefile comments in later releases (as there is for Ultrix).  Using Bob's
    version works fine.

(2) Undigestify is broken.  Typing `R' to read all digest articles, then
    reading them sequentially eventually yields a SIGSEGV.  Bob is aware
    of the problem and has a fix.  Works fine with the fix.

(3) Vanilla `vn' scrolls for each successive page for > 1 page articles.
    On low-speed modem links, or on Sun monitors (inside a window system
    or using the raw console), this is a Big Lose (I can't speak for other
    systems using bit-mapped monitors & window systems).  I submitted patches
    that enables repainting from the top of the screen for successive pages,
    if the environment variable MORE is set to `-c'.  This emulates more(1)
    in this regard.  The same patches also keep the last line of the previous
    screen as the first line of the current screen (as does the default
    scrolling behavior), in reverse video if possible (a la rn).

Now if we could only get articles left marked unread between sessions ...

Fixes should be forthcoming for the above; don't write me - wait for Bob to
release an update (I'm feeding all our fixes to him instead of posting them).
