[PATCH] e2fsck: make -y -y answer "no" to Abort?

[Eric Sandeen <sandeen@redhat.com>]

RH Bug 484913 - Change verbage of e2fsck questioning to make the "-y"
switch more useful

demonstrates:

sh-3.2# e2fsck -y /dev/VolGroup00/VolVol02
e2fsck 1.41.3 (12-Oct-2008)
The filesystem size (according to the superblock) is 14090240 blocks
The physical size of the device is 8847360 blocks
Either the superblock or the partition table is likely to be corrupt!

Abort? yes

"-y" generally means yes, take the corrective action but in this
case it stops fsck.

Below is a little hacky, but makes -y -y answer "no" to "Abort?"

I'm open to a better method if anyone has a suggestion.
