VBoxManage exec output

[Stanislav Baiduzhyi]

Hi All,

Tell me please how VBoxManage exec decides when to print a line break and when not to print.

I'm launching my command like this (bash in debug mode):
VBoxManage guestcontrol "$ARG_VM_NAME" exec --username $VM_USER_LOGIN --password $VM_USER_PASSWORD --image "/bin/bash" --verbose --wait-exit --wait-stdout --wait-stderr -- -x /mnt/shared/$WORK_DIR/guest-build.sh

And in output (below) I see that some line breaks are not reprinted by VBoxManage, but some are, and I cannot figure out what should I do if I want to make some pretty multilined output from VBoxManage exec.
