Yes, my problems with Epoch seem to center around that.  The size seems
off, and it causes Epoch to start scrolling the page when one ^N's to the
middle of the screen.  ^V causes the thing to scroll only one or two lines,
and when I hit ^L, it turns out not to have moved me at all.

When I executed (epoch::screen-information nil), Epoch reported that the
screen width and height (in character measure according to the 1.6b docs),
were around 460 by 320 or some such.  I assume this is really pixel measure,
though..

(screen-width nil) gave me 80, but the window manager (twm) gave me 76 or
so.  <--(I think.)

Any suggestions, please, please, please?

No, it's not an increment problem, but the difference between the base
size and the minimum size. In order to avoid crashing, Epoch enforces
a minimum size, which is the difference between what the screen size
really is, and what the WM reports it as, e.g. the WM is telling you
how much bigger than the minimum the window is, not the absolute size.
Alledgedly under R4 you can specify an additional value (the base
size) to get around this, but it doesn't seem to work. Debugging runs
claim that the hints are getting set correctly (i.e., base_width,
base_height are 0, and PBaseSize is set), but there's no effect.

I noticed this problem, and fixed it some time ago.  Unfortunately, it was
sufficiently long ago that I don't remember exactly which change did the
trick.  However, I believe it was the following in src/screen.c :

% diff screen.c screen.c.old
252,253c252,253
<     size_hints.base_width = 2*xs->in_border;
<     size_hints.base_height = 2*xs->in_border;
---
>     size_hints.base_width = 0;
>     size_hints.base_height = 0;


Let me know if this doesn't do it, and I'll look further.

I'm no X expert (and I certainly don't know Epoch as well as Alan), but as I 
posted yesterday, I have found and fixed this problem for my Epoch.
I believe the problem is simply that it is incorrect to set base_width and
base_height to 0 (which is indeed being done).  Instead, they should be set
to 2*xs->in_border to take into account the window's internal border.
My post yesterday had the exact diffs.

If this doesn't work for you, let me know since it may have been one of the
many other fixes I made to Epoch that resolved this particular bug.
