> The saved line length looks to be about 77 character spaces long.

Hard limit is 79 chars per line.

This is actually a hard problem to fix. With small modifications you can make 
web interface's textarea to be 79 chars width, which is partial solution.

Both menus/reply.www and menus/enter.www have this line:

 $d

Add class "editor" to it, change it to:

 $d

At end of htdocs/style.css add:

.editor {
    font-family: monospace;
    width: 84ch;
    overflow-y: scroll;
}

This works for me with my browser, but yours can differ. Just remember to press 
hard reload is your browser to load new css (ctrl-reload or similar). Next BBBS 
version will include above changes.

Does anybody have a better solution?
