This patch helps:

=============================

Now "$" matches the beginning of line.  Not quite correct (it should be
end of line), but still better than the current behavior.

Can anybody with good understanding of the editor and the regular
expressions comment on this?

The code in question is prehistoric, i.e. it appears in the first revision
on CVS.
