Tree style

[Peter Bloomfield <PeterBloomfield MindSpring com>]

The style of Balsa's trees (mailbox and thread) has changed randomly 
with various upgrades, and I now find it noisy. Lines joining unrelated 
items, like the heads of successive threads, and little square boxes 
with +/- signs are pure clutter (the latter appeared when I upgraded 
from RH7.1 to RH7.2). Since these styles aren't set explicitly in Balsa 
code (well, lines for threaded messages are, but that's all), it seems 
that Balsa follows whatever is the default, and that seems to have 
changed for the worse (at least to my eye, and along my journey through 
distributions).

IMO, the simple triangles

for `can be expanded' and

for `is expanded' say it all, and, with no lines, give a cleaner look.

Of course, I'm not a designer...would someone with a design background 
like to comment?
