In this case, I believe that it is an slrn bug.  Comparing the slrn
0.9.8.0 code with the 0.9.6.3 code for the function
generic_read_input, I see that a buffer size check that was in version
0.9.6.3 has been dropped in the newer versions.  In particular,
0.9.8.0 has:

   Slrn_Keymap_RLI->edit_width = SLtt_Screen_Cols - 1;

whereas 0.9.6.3 has:

   Slrn_Keymap_RLI->edit_width = SLtt_Screen_Cols - 1;
   if (Slrn_Keymap_RLI->edit_width > Slrn_Keymap_RLI->buf_len)
     Slrn_Keymap_RLI->edit_width = Slrn_Keymap_RLI->buf_len;

You might trying adding this check to your slrn code and if it solves
the problem, submit the patch to the current slrn maintainer.

For what its worth, slang 2 does not have the arbitray limit that
slang 1 has.

Thanks,
