Bug 54481

Description of Problem:

The /sbin/getkey program has some bugs when certain values are used with
the -c option.

If '-c 0' is used, then any message set with -m will fail to be displayed
and getkey will wait for input indefinitely.

If -c is used with a negative number, it appears that getkey will continue
to count
downward toward negative infinity.

The rc.sysinit file uses -c with -m in order to display a countdown message
to control how
many seconds to wait for input before selecting the default autofsck option
in a filesystem
recovery situation.  If /etc/sysconfig/autofsck sets AUTOFSCK_TIMEOUT to 0,
the system
will wait for input forever without displaying any message.  (This might
sort-of make sense,
as the message it would display now would probably be "Press Y within 0
seconds to force file system integrity check".  That message wouldn't make
sense in either the case where 
'-c 0' is supposed to indicate an infinite wait OR instant selection of the
default.)

/sbin/getkey could probably also use some documentation, like a man page!

Reproducible: Always
Steps to Reproduce:

  /sbin/getkey -c 5 -m $"Counting down from %d" n           (Works fine)
  /sbin/getkey -c 0 -m $"Counting down from %d" n           (No text
output)
  /sbin/getkey -c -1 -m $"Counting down from %d" n         (Countdown
forever)

Press 'n' with the above to break out of the countdown.
