Subject: [PATCH] fix bug where the countdown would be on multiple lines

Example of problem:

ATTENTION: Merging pull request #731 from remibergsma/centos7-kvm into 'master' branch in 5 seconds. CTRL+c to abort..
-n 5
-n 4
-n 3
-n 2
-n 1
-n 0

Should be compatible with more environments if printf is used instead.
