topten's so (standout) handling

This fixes the broken code that was using a boolean as an integer.
I didn't try to track down when it changed or what it looked like
before the change.  The intended effect is fairly straightforward;
just padding a bold line with spaces.  I've no idea why someone
deciced that that was useful though.

It also fixes something I broke six years ago:  tty_exit_nhwindows()
releases the termcap data needed for turning bold on and off, so
raw_print_bold() used by topten() stopped working on tty then.

Not fixed:  the code in really_done() for dealing with topten() vs
the 'toptenwin' option really ought to be redone.
