VBoxManage GuestControl with --wait-stdout or --wait-stderr deletes final characters

Description

The last character in each buffer's worth of output is deleted. This is obvious if you look at the source code, specifically function ctrlExecPrintOutput in VBoxManageGuestCtrl.cpp.

It reads in a buffer, and then sets the last character in that buffer to zero to "Properly terminate buffer" (according to the comments). Except that doing so is overwriting the last character it read, instead of adding a zero to the end of the string.
