Bug#301911: apt: when asked to continue, script aborts if y is not pressed

[james mcguire <james@westcoastbmx.com>]

Package: apt
Version: 0.5.28.1
Severity: normal

When apt-get asks "Do you want to continue? [Y/n]" pressing any key 
except Y or y will exit the program.  If the user presses any key 
besides Y/y/N/n, apt should prompt again (perhaps say "i only recognize 
Y/y/N/n").
