Dear Maintainer,

On all three versions, at my usual teletype size, I get:

$ COLUMNS=172 stty -a | wc -L
173

good catch!

This off by one bug was introduced in v5.3 (2005)

I'll apply the following upstream:

   if (0 < current_col)
     {
-      if (max_col - current_col < buflen)
+      if (max_col - current_col <= buflen)
         {
           putchar ('\n');
           current_col = 0;

thanks,
Pádraig
