OK, here's a patch to edlin which does backwards and forwards keys for at
least OS X. It should work on Solaris (I think) but my machine has not
revovered from the office DNS outage several hours ago so I can't test it (I
rely on the ESC[C type of thing which seems quite common).

edlin.erl doesn't do "previous line" and "next line" (perhaps forgivable
given its name) so back to hunting around..
