Changes cmd_print to return an offset that does not include the trailing
'\0' when the command has no arguments.

One effect of this is that it allows bind-key to work with command
sequences that contain commands with no arguments. For example, the
following bind for R does not work without this patch:
bind R send-prefix \; display-message "done 1"
bind S send-prefix -2 \; display-message "done 2"
