You mean it only stops when the last char of the buffer is at the very top
of the screen.  I don't think it's a feature.

It reflects he number of chars visible compared to the total number of chars.
That's pretty standard (Xaw with xterm does the same except it's based
on lines instead of chars.  Since Emacs doesn't keep track of the number
of lines, it would be costly to recompute it all the time).

I'm not sure I understand.  It does reliably indicate something else.

It's a bug I haven't been abloe to track down (yet).

That's not related directly to the scrollbar.  Same thing happens
with M-v and C-v.  You want something like scroll-in-place.

That's a bug.

I have a patch that fixes this bug and that fixes the size of the
thumb (because the bug is directly related to the difficulty of
working around Xaw3d's (and Motif's) insistence on not handling
a variable-sized thumb satisfactorily.  Xaw handles it just fine).

I don't find it better, tho.
