By ``bug'' in this case I meant a design bug.

It's at least a bad misfeature, and surely shouldn't be on by default
in compilation buffers.  Unlike buffers that display program sources
(where GUD uses the overlay arrow), whose most lines tend to be
indented, compilation buffers have almost all of their lines start at
column zero, so the arrow will always hide something.

That's not what is usually meant by ``customizable''.

Let me be sure I understand you correctly, Kim: are you actually
saying that this is a good feature, the way it behaves in current CVS?
