fix B12001 - ?--More--single line menu

From a bug report:
3.4.0 broke the ability to pick the only listed inventory letter when
user typed '?' during object selection and one candidate was listed on
the top line followed by --More--.

What do you want to throw? [b or ?*] ?
b - 7 +0 daggers (alternate weapon; not wielded).--More--b
<behaved as if user hit ESC instead of 'b' but didn't say "Never mind.">

(Dismissing --More-- the normal way and getting a new selection prompt
worked as usual.)  The problem was caused by changes in getobj's count
handling; the message_menu() routine isn't able to handle counts but
display_pickinv left the count as 0 while caller expects -1 for "count
not specified".

     This was a core bug but I put the fixes entry under "tty" since
no other interfaces are affected.
