extra: use the whole terminal for the crawl, and quicken it a bit

Browse Source 
Since version 6.0, with option --zero, the edit window can cover
the whole terminal.  Make use of this also for the credits crawl.

Also, shorten and quicken the crawl a bit, and make it start always
on the bottom row, instead of (for mysterious reasons) one row higher
when the terminal has an odd number of rows.

Furthermore, don't put back the key the user typed to stop the crawl.
