OK.  I'm searching slang-1.4.9 for the "strlen" function in *.sl files.
The first one I find is in smg.sl:

static define draw_centered_string (s, r, c, dc)
{
   variable len;

   len = strlen (s);
   smg_gotorc (r, c + (dc - len)/2);
   smg_write_string (s);
}

Need I say more?  I guess most users don't use Tab in the output.

Thank you for your replies.  I think we are losing an excellent chance to
do things right.  On the other hand, S-Lang will be in compatible with the
existing hacks by Debian and Red Hat, as well as with ncurses.  I hope you
understand the implications and I don't want to start another holy war.  I
guess I'll have to swallow it or make things right, and I only have time
for the former :-(
